I tend think pg_upgrade should stick to checking things that are
necessary for the upgrade to succeed. It shouldn't start being an
interactive portal to the release notes for aspects that are merely
recommendations. I'm not necessarily against having such a facility
somewhere. But not everyone uses pg_upgrade, and not every user of
pg_upgrade reads all the messages.
