It *should not* be a bad idea - or, put as a question, why *should* it be a bad
idea? Logically, where is the problem? If the implementation is inadequate,
that's another matter, but where is the problem *logically*?

And what was wrong with the Emacs 22 behavior (implementation)?

If some feature was added for Emacs 23 that broke that behavior, and then you
say that things are too complex to use both `set-face-attribute' and Customize,
then back out that misguided feature until things can be done right. Things
seemed to be fine, before.

Adding some feature, no matter how worthy (multi-tty, Unicode), should not be an
excuse for breaking existing behavior, as if that were somehow inevitable
collateral damage.
