Apart from another database object, --logical-replication-slot-only does not provide
the "perfect" copy. As you might know, some attributes like xmin and restart_lsn
are not copied, it just creates similar replication slots which have same name,
plugin, and options. I think these things may be confused for users.
Moreover, I cannot come up with use-case which DBAs use the option alone.
If there is a good one, I can decide to remove the limitation.
