The real question, to me, is "Was the RF mount design a good decision?"
The RF mount, when it was released in 2018, with its 54mm diameter and 20mm flange distance, was touted as having big benefits. The mount specs where going to unlock a new era of compact, optically great and affordable lenses - things that would be impossible on e.g. Sony's 46.1mm E-mount. I would argue that the last 8 years have proven something else.
Full disclosure, I was on my photography hiatus when Canon went from EF to RF (shot in earnest 2008-2013 then picked it up again in 2023-current) so I totally missed the justification as to why the RF mount was adopted.
You mentioned that they touted the RF would "unlock a new era of compact, optically great, affordable..." which kind of flies against the "you can have 2 out of 3" engineering principle. If everything could easily be small, optically great, and affordable, then someone would have done it by now and dominated the camera world. But right now Canon, Nikon and Sony all have their solid fanbases.
I went on an admittedly shallow dive to try and find any press release or article from the 2018 era that might indicate where Canon promised those three things, and couldn't really find it (if you have a link feel free to post).
I did come across this:

This was a September 2018 coverage of the first four RF lenses released. The MSRPs are higher now, but even then they were not inexpensive (save the non L lens). From the official Canon press release located further down the DP Review article:
The Canon RF 50mm F1.2 L USM will be available in October 2018 for an estimated retail price of $2299. The Canon RF 28-70mm F2 L USM, RF 24-105mm F4 L IS USM and RF 35mm F1.8 MACRO IS STM will all be available for purchase in December 2018 for an estimated retail price of $2999, $1099 and $499.99 respectively.
And even the top of that Canon Press release, where they do tout the benefits of the RF line, I don't see a mention of lowered costs/affordability:
MELVILLE, N.Y., September 5, 2018 – Helping to rewrite the rules of visual expression, Canon U.S.A. Inc., a leader in digital imaging solutions, today introduced a variety of new RF lenses and accessories to accompany the newly announced EOS R Full-Frame Mirrorless Camera System. The four new RF lenses are built around Canon’s new RF mount, which features a large 54mm diameter and shorter back focus distance than on current EOS DSLR cameras. The new RF mount enables new possibilities in optical design and lens formulation, allowing for faster and lighter lenses with higher performing optics.
The four new lenses, the Canon RF 28-70mm F2 L USM, RF 50mm F1.2 L USM, RF 24-105mm F4 L IS USM and RF 35mm F1.8 MACRO IS STM capitalize on the robust optic foundation of Canon’s new EOS R system. The design behind Canon’s new EOS R camera and RF lens system started with the concept of the optimal rear lens element diameter and shorter distance (back focus) for a Full-Frame image sensor....Show more →
Look, I'm also not thrilled at paying more for camera gear overall. But I can't find evidence of Canon saying that the change to RF would make their lenses more affordable. If they were touting that, I'd be right alongside you calling them on that fallacy.
