Now that Sigma has a bunch of RF-S primes (12/1.4, 15/1.4, 23/1.4, 30/1.4, 56/1.4) I don't think its a problem.
I think Canon is actually right in keeping the lens costs down for RF-S.
Long ago I realized that after investing beyond a certain point in multiple APS-C lenses, the total cost can exceed the price of a more capable full-frame system.
A zoom on full frame can sometimes cost less and yet be more useful than multiple primes on APSC
Honestly, RF-S users have greater choice today than EF-S users ever had during the entire DSLR era, which is something I would not have expected a couple of years ago.
Sigma offers a complete range of excellent fast prime lenses for Canon RF-S, including 12mm f/1.4, 15mm f/1.4 (replaces the 16mm), 23mm f/1.4, 30mm f/1.4, and a 56mm f/1.4.
And of course, you can adapt any EF-S lens to work with native performance on an R body.
You could even argue that several of Canon's full frame STM primes like the 16, 24, 35 and 50 are small, light, and fast enough to be useful on APS-C.
Sure, it would be nice to see Canon join the fray, but I am not holding my breath.
The good news is that Canon's mirrorless APS-C customers are being well supported by third parties. Sigma in particular is a world-class lens maker today, easily able to hold its own against the camera makers in terms of optical and mechanical quality.

I think Canon is content to let Sigma make the lenses for RFs, but I think they would be smart to make a few more telephoto options especially with the R7 as a potential action camera if the rumors of the next version having a stacked sensor are true. Adding a 85 f/2 prime would make a lot of sense, whether it comes from Sigma or Canon and some good telephoto zooms like a 50-140 f/2.8 and something like a 65-250 f/4-5.6 would be a really nice addition to the lineup. That said, I generally agree with Gary that there is a pretty good line up for APS-C shooter with the RF mount.
I would buy a used EF 50mm f/1.8 II before I spent a $400+ on a sigma 56mm f/1.4. I already have an EF 100L that adapts nicely. I have considered the Yongnuo 23mm f/1.4. That about rounds out my need for primes. Canon doesn't need to make RF primes for me.

You can switch, you know.
You can block him you know. Since you are so affected.
I dont like this kind of character assassination type posts. It does not add value to anyone. OP's question is entirely reasonable, there are indeed few RF-S first party lenses for now.
OP uses lower end Canon gear, and low end gear certainly comes with significant drawbacks or the manufacturer will never be able to hit the price point and nobody will bother buying the higher end stuff.
Other manufacturers like Sony dont even bother making low end cameras like the R50, so big props to Canon even though the R50 has many flaws like a tiny buffer.

Character assassination? Really?
I’m really just asking a question based on his post history, which maybe you don’t know. He has so much lower-end Canon gear that he could easily sell some of it and get the gear that would solve the things he complains about. Yet, you can almost set the clock on him complaining again.
We all have our quirks here. This is his. Mine is constantly doubting the gear I have, hanging on to too much of it and then wondering what horrific things will befall me if I let go of some of it and bothering others with that here.
And, yes, Canon’s offerings are slim. They have been for a long time and Canon has shown no sign that will change. So, better move on if that’s an issue for someone.
I'm hoping that optically/electronically advanced companies like Sigma develop more APS-C lenses for Nikon and Canon in the future. I could really use a high-grade 16-80 or 85 f/4 with OS for example.

The EF-m system had both the 22/2 and 32/1.4
Why won’t canon just mount those into METAL RF-S mounts… I don’t want no more plastic!!!
So sick of paying good money for plastic mounts !!
Anyone else share the same frustration??
While not necessarily a prime lens, I used the Tamron 11-20mm f2.8 in RF mount before I sold my R7. IQ from that lens was not bad, and it had a metal lens mount. Here are some samples from some images I shot with it:

Sigma does now have the new 17-40mm F1.8 DC | Art (a 27-65mm f/2.8 equivalent on Canon 1.6x crop).
This is the spiritual successor to Sigma's 18-35mm F1.8 DC HSM | Art for DSLRs, and manages to increase the zoom range, improve optical quality (per Sigma) while shaving 30% off the weight of the original.
I expect an updated 50-100 f/1.8 will come fairly soon to match this lens. The original HSM model was a heavy beast and had no stabilization, so hopefully Sigma can improve both of those areas.
For what it's worth, Sigma is the only company (to my knowledge) to make pro-grade high speed zoom lenses for APS-C. Not even Fujifilm makes an APS-C zoom lens faster than f/2.8, which is only an f/4.5 full frame equivalent in terms of depth-of-field control.
IMO, Sigma's lens lineup almost single-handedly makes a camera like the forthcoming R7 Mark II viable as a full-time professional imaging tool, and not just a niche camera giving wildlife shooters extra reach.

You just have not figured out that the OP is a whining troll. He buys the gear that he complains about incessantly. Offer him all the feedback you want, and see where it get him.
I enjoy my R7. It's tiny and can use my RF, EF, and EF-S lenses—making it ideal. I, like most R7 shooters, also use FF R series and wouldn't buy a new optic unless it is shareable between cameras without forcing an APS-C crop on FF. I own the RF 24 1.8 and RF 50 1.8, and they are tiny and work well on both APS-C and FF and have a metal mount. If you really want a small image circle RF-S prime, Sigma is doing a good job bringing them to market.
Seems to be a lot of hate here towards me for raising issues with canon.
Says more about you fellas
I have the sigma 1.4 trio in ef-m
It’s ok, but they’re big and bulky
The ef-m 22/2 and 32/1.4 are superb
They were built to cover aps-c sensor on mirrorless bodies. I don’t understand why those two lenses cannot be produced for rf-s mount??
I’ve not actually researched this, but am I right thinking every single ef-s lens has a plastic mount??
I’ve bought a used 14-30 for the R100 for a upcoming trip to Paris next month
But I might instead take the M50ii with 15-45
Seems bizzare that the lens offerring in rf-s is noticeably worse with each mount release
As for crop DSLR’s.. canon made some fantastic glass.
