Sony decided to keep a rather small mount and use it on full frame, Canon took another approach saying it will give them advantages in lens design ..
The EOS-M was selling well in Japan mostly, however. With the small size of some of the smaller EOS-R camera's, which have the same flange distance as the EOS-M series, there is no need to have two ranges now. I reckon the EOS-M was a camera to test the waters and to experiment with the possibilities of a pure EVF-camera, but along the way they realized that for economics it would be better to have a single mount for all EVF-based cameras, especially as the EOS-M only sold well in Japan.

With regard to future possibilities, and make the mount last as long as the EF-mount, I would think the answer must be yes.
Just look at the original Canon-adapters for EF to M, they narrow quite a bit at the M-end, while the EF to R adapters are essentially the same at either end, as the diameter of the effective opening is the same too. However since that opening is much closer to the sensor, it is a lot less restrictive.
In addition there are the additional contacts for further expansion when new technology becomes available, and I am sure that those extra contacts were conceived with specific possibilities and opportunities already in mind.
Gear: Canon EOS R with 3 primes and 2 zooms, 4 EF-R adapters, Canon EOS 5 (analog), 9 Canon EF primes, a lone Canon EF zoom, 2 extenders, 2 converters, tubes; Olympus OM-D 1 Mk II & Pen F with 12 primes, 6 zooms, and 3 Metabones EF-MFT adapters ....
