Sorry I was unclear. When I said "not thought-through", I meant, you
need to start with the _reason_ we need to break pg_upgrade in an
upcoming version, then we can start to plan how to do it. The logical
replication idea is a good one for getting us through pg_upgrade
version-breaking releases.
I am fine with breaking pg_upgrade, but I just don't see the pending
reason at this point.
