In light of the above, it is perfectly reasonable to require, at least

pg_upgrade does that, kinda.  I'd like to have something better, but
in the absence of that, I think it's quite wrong to think about
deprecating it, even if we had logical replication fully integrated
into core today.  Which we by no means do.

I would much rather see more brain power put into pg_upgrade or in place upgrades than logical replication (as a upgrade solution).
