This I think was pretty noncontroversial.

It doesn't seem to me that this really buys much.  What we really want
is a way for a dump/reload to remove OIDs from tables that formerly had
them; otherwise people will not easily be able to migrate their existing
tables away from having OIDs.

Not unless you want partial pg_restores to break.
