Will we ever see a 22mm f/2.0 for RF?

The EF-M 22mm f/2 was one of my favorite lenses on EF-M. It was equivalently almost exactly a 35mm focal length which is classically the ideal focal length for street photography. Together with its bright maximum aperture, Canon gave Fujifilm cameras some serious competition for their street-photography models like the X100 series.

Fast forward to today, a lot of EF-M lenses got ported to RF, but they never ported the 22mm. Was it too good for an inexpensive middle-class lens? We only got the 16mm and the 24mm. And you're probably gonna say 2mm doesn't make much of a difference but the 22mm was also a pancake lens. Paired with an M6II camera it was the perfect, unobtrusive, easy-to-carry combination for street photography.

Please Canon, bring back this excellent lens for RF-S. Pair it with a retro-style camera and you gonna have street photographers and vloggers buy it like hotcakes.

I put it on my M3 and almost never took it off.

I really doubt any M series lens was "porter" over to become a RF lens. SImular FL doesn't necessarily mean it is the same lens only retrofitted to RF mount. The demands of R series is greater than EF-M ever was.

It remains to be seen whether Canon will ever make an RF-S prime. So far their RF-S lineup doesn't even approach what they offered in EF-M, which itself was widely criticized for being a small group, though it included some serious winners like the 22mm f/2, which is my favorite lens for indoor and group shots.

I think you are comparing apples to oranges by comparing the EF-M lineup to the RF-S lineup.  A better comparison would be to the EF-S lineup.

The EF-M lineup needed to be a full lineup of focal lengths.  You could not use EF/EF-S lenses without an adapter.  

The RF-S mount bodies are more similar to the EF-S mount DSLRs than EF-M mount bodies.

If you're looking at it from the standpoint that there is a wide selection of lenses that can be used on this crop-sensor body and a few specifically for it, then yes, EF-S is more like RF-S than it is like EF-M. But there are considerations for RF-S lenses beyond those for EF-S lenses, and those considerations are akin to those for EF-M. The primary motivation for EF-S lenses was to reduce cost compared to equivalent EF lenses. There was little to no consideration for making the lenses more compact or the overall package more ergonomic - e.g. my EF-S 55-250mm isn't significantly smaller or lighter than my EF 75-300mm. But with RF-S lenses there is clearly a size/ergonomic motivation in addition to a desire to reduce the cost, as evidenced by the barrels that skinny up once away from the mount, and in that respect they're more like the M system.
