That's funny, I was going to say the opposite...I think we should
clarify it to say that in the cases where it makes sense to have a
libfoo-compat package, there's no need to bend over backwards to try and
make libfoo-devel and libfoo-compat-devel be parallel installable,
because there's just no important use case for it. There is no reason
you'd need to compile one code base against two different versions of
the same library, so there's no case where you would need to have both
-devel packages installed simultaneously.

I think we should be strict about trying not to package multiple majors
of the same library wherever possible, but where it's pretty much
unavoidable, I think it's perfectly fine for the -devel packages to
conflict. In fact I think it's better to leave them conflicting than to
hack them up with patches to make them not conflict; that's always going
to be a hack job, nothing clean. The library thinks it's called libfoo,
not libfoo2 or libfoo-compat. I think the guidelines should reflect
this...they should explicitly say that a -devel package conflict is fine
and indeed recommended in the specific case of packaging multiple majors
of a single library.
