Personally, I think the point of a compatibility GUC is that at some
point in the distant future we can get rid of it.  If we default to
the old behavior thats going to be harder to do.  +1 for defaulting to
the new behavior.

[ Id actually vote for _not_ having a compatibility option at all, we
change more major things than this IMHO every major release. (And even
then some major things in minor releases, for example the removal of
Safe.pm) ]
