And we really do sometimes have the superset as R also imposes.  Right now
the only reason we are rebuilding is ... so that R (at run-time, when loading
the package) sees it as being produced by R (>= 3.0.0).

I still think that is wrong but you ipso-facto get the right thing to
happen.  But for my packages, I do make this explicit.
