That's not a design, that's just a very arbitrary kluge. And it doesn't
solve anything at all that we need to solve today, because you can
already assume that you're running on >= 9.1 just by the fact that
you're writing an extension. Having a solution for this in time for
9.2 will be plenty soon enough.
BTW, I don't see any good reason to distinguish "core" requires from
non-core. If anything, the spirit of an extension proposal should be
trying to reduce the distinction between "core" stuff and "not-core"
stuff, since part of the point of extensions is that features might
migrate across that boundary.
