I'd like to see the inverse ... a pseudo ground glass presentation.
By that, I mean instead of highlighting / pointing to the area in focus (with boxes, colors, arrows, etc.) .. defocus the rest of the image. Electronically adjustable from slight to heavy. This is likely not on someone's radar and won't happen. I suppose it could be implemented via firmware, though.
But, with the RF, we have a partial patch for misalignment / alignment ... and we have the view that doesn't show us our DOF, so we have to "imagine it" in our mind's eye, per our understanding of our aperture setting. The point being that we function without seeing everything, yet we know what we have. Similar to sighting a firearm, the visual effect is learned for seeing the sharp vs. oof.
Many folks haven't shot with ground glass, and have no idea what that experience is like. But, depending on the variance in the chosen glass, focus can "pop' into place really nice, imo. In a "Leica" esque kind of manner, NOT having colored contrast or boxes turning green or arrows lining up ... less is more ... the experience (electronically emulated) of ground glass would allow you to see your focus very clearly and still have the view of the framing composition. Our present "aids" (boxes, colors, arrows, etc.) are all interruptions to the scene. Losing those visual interruptions would be Leica-esque ... rather than more like Nikon or Canon or Sony or Panny, etc. Given that DFD technology is in existence to confirm focus, a visual presentation of that, inversely presented would provide for a clear visualization of that which is in focus ... no other (distracting) aids required.
You could electronically choose from none / off (allowing you to visualize dof) to mild to heavy (making the focal plane very easy to see) ... it would be the most innovative move that would use today's technology to harken back to the ease of use legacy approach. Additionally, you'd clearly see the plane of focus, not just a focusing point. So, where you have field curvature, etc. ... it would reveal well also. Part of the M experience is that the RF offers an experience that is not found elsewhere. An electronic ground glass implementation in an M body would be an experience, not found elsewhere as well, keeping the ethos of the M as a unique experience.
And, since it could be electronically implemented, folks could roll with the other aids if they so choose. But, an electronic ground glass ... that could be the cat's meow for focusing aids, imo.

Hm how is Canon's focus guide any more obtrusive than the rangefinder patch in an M? One has two indicators lining up, the other has two images lining up.
Imo the Canon solution makes it easier to keep track of the overall composition as it's easier to see when the indicators line up, so you have to concentrate / focus (!) less on the MF aid. And it takes up less space in the viewfinder.
The virtual ground glass idea sounds nice, but also very complex to implement. Is this supposed to apply Gaussian blur with different strength depending how far in- or out of focus the image is? And how do you deal with different DOF depending on the lens used and aperture set? Seems hard to create a consistent experience.
It's quite likely that Leica will "just" recreate the rangefinder patch digitally (i.e. two images lining up) but they'll probably enable you to move the patch around. It will still be a bit weird compared to the optical rangefinder due to DOF, so imo would be better to create something new that solves the same problems rather than trying to imperfectly mimic an optical solution. But happy to be convinced otherwise by their implementation
