Do you even want to draw that line in rawhide? To me, rawhide is
dangerous enough that trying to add delta updates on top of it is just
asking for (more) trouble.

I think that -updates* is perfect for deltas, because the latest package
is almost always going to be an iteration on the previous version(s).
But rawhide might be a complete version jump, or changing toolchains, or
trying something just plain whacky. The potential for space saving due
to commonality doesn't seem to be there for rawhide.
