I didn't know that was possible.  It's perfect.

"alternate-emphasis"?  But if faces can be aliased without obsoleting,
then 'basic' can continue the old names with maximum semantics.

And since I don't think flex has much need for "alternate-emphasis"
, it can continue to use the old names.

The main issue, for me, is letting 'flex' emphasize the part of the
string that matched the pattern, so that users of flex can get
visual feedback (like Drew, albeit a little longwindedly, explained
here: https://lists.gnu.org/archive/html/emacs-devel/2019-11/msg00261.html).

This is the core of my proposal: to improve usability of the new
flex style by default.  With your face aliases idea, the patch
becomes even simpler, and can be contained to just 'flex' (or
expanded to substring and p-c-m if their authors/users find
acceptable).
