This is interesting. The new lens is considerably more compact than the older 16mm f/1.4, and at 15mm is a more standard focal length for Canon (an exact 24mm equivalent FOV with Canon's 1.6x crop).
Back when I had my M system, I had a couple of the other Sigma APS-C primes, but I never picked up the 16mm due to its unwieldy size. Assuming this new lens holds up optically, it looks to be a significant improvement.
I'm not sure how many people are going to buy a 24/2.2 equivalent prime for the RFs bodies, maybe R7 and R10? Canon markets RF downscale other than the R7.

Why not? Canon has no primes for the current crop system -- like, none at all, and none of the zooms are faster than f/3.5-6.3. The EF-M system, all its numerous shortcomings notwithstanding, at least had a couple of bright primes; here, it doesn't look like Canon is even trying.

Well it is a 24mm f/2.2 FF equivalent, so it could be used as a landscape lens. It could be used for group portraits. Sigma has what I believe is a quite popular 24mm f/2 i-series lens for L mount and Sony E mount. This would be a similarly performing lens for Canon APS-C.
This is obviously a replacement for the 16mm f/1.4 DC DN and I think that replacement makes sense. They already have the newish 12mm f/1.4 as a DC lens, so that will be part of the series. I suspect that the 56 f/1.4 DC DN and the 30 f/1.4 DC DN will also get replaced with a DC version. As they do so, they might tweak the focal length as they did here. If I were guessing I would think the 30mm will stay at 30mm and the 56 might well be 55mm. That leaves an interesting gap between 15 and 30. I think we might well see a 22mm that is about a 35mm equivalent and we might see a 10mm for a wider angle at some point too. That would give a fast RF set for APS-C from Sigma of:
