I already have a couple more ready once this has stabilized...
I personally don't agree that they have no value at this point. At least
the pg_basebackup tests test paths that are not executed *at all*
otherwise and which are not trivial. To my knowledge it's the only thing
in our tests that exercises walsender and wal_level != minimal.
