You must have a lens thinner than 20mm to do that. I can imagine such lens to be possible to make but I doubt that this would be a factor (and you gain a few mm only anyway).

I am referring to lenses such the EF 40mm, EF-M 22 or EF-S 24. These are lenses that you take when you want to travel light, other focal lengths are possible with compromises.

They would still fit. On the other hand, one could have a 50mm pancake.

I am not sure that this applies for all of them. If the diameter is somewhat smaller, there is no problem. In any case, I am not interested in other mounts.

The Diameter is not the main adaptability problem but the flange back distance of the other mounts. You can adapt from longer mounts to shorter but not the reverse.

You can do the reverse if the diameter is small enough. Having said that, I do not really care about other mounts. I have heard that certain K mount lenses would interfere with the mirror; other than that, they can be adapted to the EF mount. Without a mirror, that would not be a problem.

In other words the EF-M mount is more versatile, it open up more possibilities.

That is another question. I am not sure what Canon would do - just saying that the EF mount is an option.

Yes is an option but it doesn't make much sense to me.
You have to ask yourself why Canon designed the EF-M mount large enough to fit a FF sensor?

I do not know. Maybe to have more options later. BTW, it covers in barely. This could still create problems with fast lenses.

Nope, Sony E mount is a hair smaller than EF-M yet there is no problem with fast lenses.

Ask again why Sony didn't use their legacy Minolta SLR mount with the FF MILC cameras.

I stopped asking myself why Sony do what they do a long time ago.

Is a rhetorical question, making the case why Canon would use the EF-M for FF.
Another way to look at it is that Canon will keep making traditional DSLR EF mount cameras.
They will just expand the M series with a FF sensor next year and the corresponding FF EF-M lenses.
