Basically yes. The 12 sizes of wide accents which are in the cm layout
right now are my own mf work, based on the original cm and the yhmath
versions. It will be easy to change their number and/or width progression.

Well, I meant to say that they will be missing in vf implementations based
on the currently available font sets.

We currently have \Hat \Bar in MSP, but not \Bar \Hat, so this is an
interesting information.

I'll have to look that up too

Yes, I think this is the case.
