I don't really understand the problem here, probably because I'm not
sufficiently versed in themes, but just in case, you may want to give
a more specific example of what behavior you're trying to get, what you
tried (presumably something like ((t (:inherit foo)))) and what you
don't like about the resulting behavior.

That's the way the interaction between custom settings and Lisp settings
are defined, because it seems like the only "sane" way to handle it.

Probably something that should be fixed.
