I'm quite sure that the original argument for using in-place updates
for this was not wanting a full-database VACUUM or ANALYZE to update
every tuple in pg_class.  At the time that definitely did lead to
more-or-less 2x bloat.  The new information we have now is that that's
no longer the case, and thus the decision can and should be revisited.
