The only one that's problematic is; contrib modules are
already installed in $libdir.  I still think that installing in $libdir may be the most reasonable solution, assuming
that the delta involved isn't too great.  Yeah, we would have to
back-patch the changes into every release branch we want to test
upgrading from, but how risky is that really?  The *only* thing it
affects is the regression tests.

Maybe I should produce a draft patch for moving that way,
and we could see how big a delta it really is.

Possibly, but it'll always be more impoverished than the regular
regression test DBs IMO.
