Canon's focus confirmation (focus guide) is excellent and was already present on the 2018 Canon EOS R.
Just to be clear though, it normally only works for electronically coupled lenses, in the case of the M to RF Shoten adapter it is the adapter itself that features electronic contacts.
I am not sure whether Shoten adapters for other mounts do the same. I don't believe so, but perhaps somebody can confirm.
From what I can see on eBay (seller shotenkobo) the Shoten Leica M to Canon RF adapter is the only Canon RF adapter with electronic contacts.
Contrary to Nikon Z where multiple electronic adapters seem to exist. See also article below: "SHOTEN releases nine types of mount adapters with electronic contacts for Nikon Z mounts". https://en.pronews.com/news/20260330124414664.html

AFAIK, yes the Shoten adapter with electronic contacts is the only way to adapt Leica M mount lenses to Canon RF with the Canon focus aids, but older SLR lenses can also be adopted by using a chipped adapter to Canon EF mount and one of the Canon EF to RF mount adapters. Also all of the Cosina made Zeiss lenses with EF mount can be adapted with one of the Canon EF to RF mount adapters. I am still a big fan of a number of these lenses, but they aren't small like Leica M lenses. One nice thing about them on Canon RF, however, is that they almost gain an aperture ring. You can adapt them with the Canon EF to RF mount adapter with the control ring and control the aperture on the adapter instead of through the camera. Oddly the Nikon F mount versions of these Zeiss lenses lose the function of the aperture rings they have always had (they must be set to the smallest aperture with the aperture control by the camera) when they are adapted to Nikon Z.
I am not sure how many people appreciate the Canon and Nikon focus aids (I know I do quite a bit), but I think that appreciation should tell Leica something important about the EV-2--namely, they might want to have it include PDAF sensors and utilize those PDAF sensors for focus aids. As we see the AF of Leica SL cameras mature with the SL3-P, Leica ought to be able to provide such focus aids and personally I think it would make a big difference for the EV-2 to have them.
R8 is excellent with Canon RF af lenses as a small camera, but using R8 with Shoten vs EV1 or SL3-S or CL, it is much easier to use the Leica cameras for manual focus from my experience... That is similar to using Panasonic S1R II vs SL3-P discussion eg much simpler menu/button approach with Leica... Hopefully, Leica will add more mf confirmation for the EV2... I prefer the non-box method with the pets as they turn their eyes/head so quickly, so Canon mf box blocks the view for me...

Fair point - but I am less optimistic that Leica is going to do it since they want to protect the SL business and avoid in-house competition of the EV series with the SL series. Or in other words: they will continue to have the EV series be worse with focus aids than the SL series. IMO the EV-2 will improve potentially only by having IBIS (I don't think the M12 will receive it!) and some kind of minor focus improvement compared to the actual system.

No disagreement. Focus confirmation is in my opinion more accurate than peaking and a much better user experience than magnification.
FWIW, Hasselblad has it as well since the X2D. It is called focus indicator.

With which EVF cameras (excluding Nikon and Canon models that feature a focus indicator) is manual focusing easier than with your A1, and why?
My Leica SL2 and SL3 bodies are a lot easier for me to manual focus. In all honesty, I don't know the exact reason other than it is easier for me to see when the shot is in focus than it is with the Sony. I used to shoot Fuji X series and those were great - very easy to manual focus. While it has been a number of years since I shot those, I seem to remember (I could be wrong on this though) that when an image was in focus, it just "shimmered" a bit. Admittedly, I do remember that kind of shimmering, but am not 100% sure if it was the Fuji system or not, but I don't know what else it would have been as I went from Nikon DSLR to Fuji to Leica & Sony. My eyes are not getting any better either though, so part of the ease with the Fuji system may have been that I could see better at the time that I used that system.
