Even if the FF mirrorless setup had an EF-M mount (if that's even possible), current EF-M lenses would only cover a crop image circle -- they might be usable on a FF mount but they certainly won't be desirable for that application.

I doubt that Canon would design the FF MILC mount to take EF-M lenses.  But if they use the same flange focal distance and throat diameter (which is possible with EF-M mount specs, albeit barely), then APS-C MILCs could directly mount FF MILC lenses, just like EF lenses on APS-C dSLRs, and that certainly would be desirable.  Or they could use the existing EF mount, which I think is the most likely option.  The third option – a new, dedicated FF MILC mount that requires an adapter for EF lenses and likely won't mount on APS-C MILCs (an ultra-thin uber-unergonomic adapter notwithstanding) – is the least likely option.
EOS 1D X, EOS M2, lots of lenses

No no, that's for after they let me down with some ring lite macro collapsing STM variable aperture focus by wire plasticsauce nutty focal length disasterpants of a lens.   

And I have my own graphic for that, thank you very much.   ;)

The solution may be coming, if a fullframe mirrorless is on the way.  I went back to the 2012 lensrental articles on 5DIII auto focus and it turns out the 50mm f1.4 focuses just fine with contrast detect AF in Liveview.  No need for a new lens.  Just a new camera with an EVF.  😊

If Canon's answer for the EF 50 f/1.4 USM replacement (which should cost between $399 and $799 depending on feature set) is to buy a $2K+ new body, they can stuff it.

And even if they did that, f/1.4 on that lens is not terribly usable and the protruding/damageable inner barrel (i.e. the externally focusing design) would still be around.  No sale.

I don't believe the M mount would have an adequate image circle to cover full frame. I could be wrong.

It does. It's almost identical to the Sony E/FE mount size.

Interchangeable Lens 1

    SKU: 2309C005AA
    made in Japan

Interchangeable Lens 2

    SKU: 2439C005AA
    made in Japan?

35ish and 85ish EF-M prime lenses? ::)

Are EF-M lenses made in Japan?

I think so. I'm picking up my M5 today, so I'll let you know what it says on the lens. But with a full frame mirrorless body that's supposed to come out next year, along with how well the M5 has been doing (especially compared to the earlier abomination in the M line) it would make a lot of sense for Canon to bulk up the EF-M lens line up ahead of time. The only primes are the 22 and the macro lens. Slim pickings. Rokinon's EF-M 50mm has seen a lot of love though. There is a 16mm EF-M lens out now as well third party.

All EF-M lenses are currently made in Taiwan, even the excellent metal-bodied 11-22.

It is perfectly possible to make a full frame image circle with a back focus of 18mm. The lenses would need to be a concentric design as much as possible and the lens image circle preferably larger than the current EF system. The optimum flange distance is currently believed to be between 17 - 22mm. An industry group made up of people from Sigma, Sony, Zeiss, Leica, Fuji, Cooke, Angenieux, Panavision & Arri (but not including Olympus, Canon, Nikon & Panasonic) have already discussed the merits of such a standardised approach although I doubt a single common depth will be adopted.

Sony have proved its possible.

if this is it, you should not be disappointed ;)

I’m disappointed in the dynamic range of PC2328, whatever it is.
