No, I'd say the big reason it hasn't happened is lack of consensus on
details of how the feature should work --- notably, ought the creation
date be preserved across a dump/restore? Doing that would require
exposing some method to set the creation date from SQL, whereupon it loses
value for some purposes because you can never be sure that what you're
looking at is the "real" date and not something somebody frobbed later.
OTOH, losing all your creation date info during dump/restore is annoying
too.
