Yes.  My recollection of the thread a few years back around Richard's changes to
setting face attributes informs me that those who are familiar with face
implementation (e.g. Yidong) are much better placed to think about how these
things might be done.  I remember it seeming to be fairly complex.  It is also
they who would decide _whether_ such things should be done.

I don't think so, but I could be wrong.  AFAIK, you can do this at any time to
get the default spec:
(get SOME-FACE 'face-defface-spec).

(I thought there was also a way for a user to restore that default in Customize,
but it seems I was mistaken about that.  You can `Show Lisp Expression', but
that just shows the current value, not the default expression from the

I don't think we need to - see above.  But again, I'm not going to try to get
involved with implementing this.  If those who are face-implementation
knowledgable are interested they will get involved.  If not, so be it.
