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.
