Most people familiar with the systems know that EF-M to RF adapter is not possible because:

EF-M flange distance: 18mm

RF flange distance: 20mm

The EF-M lens would have to sit 2mm inside the RF mount.

I made a video about this to explain to people who are newer to cameras:

Or...there would have to be glass in the adapter.

Yep, I cover that possibility in the video as well. But it is very unlikely that anyone would ever make this since EF-M lenses only cover crop sensor and none of the EF-M lenses were amazing enough to be worth the trouble.

There are excellent EF-M lenses, but an adapter with lenses would very likely dilute the quality. Might be similar to an FD to EF adapter with lens which I once tried and which turned out to be pretty useless.
