If this feature is of any use, surely we should assume that more than
one extension will use it.  If those extensions are separately developed,
there's nothing preventing name conflicts.  I would rank the odds of
two people writing "my_replication_extension" a lot higher than the odds
of the core code deciding to use such a prefix.

What's more, what happens if we decide to migrate some such extension
into core?  A hard and fast division between names allowed to external
and internal features is just going to bite us on the rear eventually.
