    Among other things, it would allow people who see such a form to do C-h f to
    get doc about it.  Which is to say, we'd get to document it (the doc could
    explain whether the alias works when put on the `face' text-property, or
    whether it only affects Custom face settings).

Don't all face aliases work wherever a face name is used?
I don't see a use for this sort of documentation.
