The odds are quite high. Couldn't we introduce a new wal_level
value instead?
wal_level = logical_only
I think this thread shows that logical replication no longer is a
superset(?) of physical replication. I thougt that we might be
able to change wal_level from scalar to bitmap but it breaks
backward compatibility..
