I never suggested otherwise. In fact, I said the same thing.
And I said clearly that all such fossils should be removed
from the existing code.

Again:

 IOW, let's not confuse the effort to remove such fossils
 from the Emacs code with the idea that no one should ever
 use face variables. Use them in the (rare) cases where
 they are useful; don't use them otherwise.

Again, that's just what I said. Please reread. No one has
claimed that the rule is "wrong for the general case".

And Richard didn't say that, BTW - I did. He merely
acknowledged that there might be such cases, and that the
particular use case I pointed out is reasonable.

The point is that we should not just provide the rule, but
also explain it. And to do that in the Elisp manual, not just
in some source code comments somewhere.
