[Brightcolours]

Gee I do think that size wise full frame mirrorless makes perfect sense. They are about the same size as the OM cameras of yore. With the smaller lenses you get a decently small system; with the larger ones I don't find that having more camera to balance to lens is overall desirable (except perhaps with superteles).

 

And most of all I much prefer a decent EVF for manual focus (and prefer the accuracy of on-sensor AF, even if it's slower, for very fast lenses.

A DSLR has good ergonomics and a good grip, usually. Easy to operate the not so tiny buttons and such. So just shrinking the body to a more clumsy size but having bigger, heavier lenses, I don't really see the sense in that either.

 

It is fine if you prefer an EVF. Personally I prefer an OVF. And I have no problem manual focussing 55mm f1.2 lenses on it, and the very fast PD AF seems to be spot on.

Tastes differ...
