Sorry, I don't follow -- examples of what that had hundreds of faces?

I'm saying that finding the faces that inherit from a specific face is
not prohibitively expensive -- iterating over all the symbols and
finding that info would be pretty fast.  If it's not, then extending
defface to keep track of this information would be simple enough, too.
