I'll have to catch up on the thread to digest that reasoning and how it
applies to decoding vs. replication. But there don't seem to be changes
to START_REPLICATION for twophase, so I don't quite follow your point.
Are you saying that we should not be able to create slots with twophase
at all until the rest of the changes go in?

I started this thread because it's possible to create a slot a certain
way using the SQL function create_logical_replication_slot(), but it's
impossible over the replication protocol. That seems inconsistent to
me.
