Yes.  People hit this _constantly_ in a lot of ways.  Like "why am I not
getting debuginfo packages".  The theory is that you might want to build
with some other set of macros, which is why rpmbuild doesn't just
require r-r-c.

I think this is foolish, and that we should just fix rpmbuild: if you
wanted some other set of macros, start by rebuilding rpm to require
something other than r-r-c.  The counter-argument is - and I find this
completely baffling - that it's easier to replace packages than rebuild
them, so that instead rpmbuild should Require: system-rpm-config and
then r-r-c happens to be what provides that by default.  Which, sure,
that's also a thing we could do.

Either solution would be better than what we have.
