When I wrote pg_upgrade, I assumed at some point the value of changing the storage format would outweigh the value of allowing in-place upgrades. I guess that hasn't happened yet.
It reminds me of TDE, which is an good example of that, in a way. It requires pg_dump or logical replication to go from unencrypted -> encrypted. If core were to have something like that, I guess pg_upgrade could technically support it, but it would be equivalent to pg_dump. We've all been spoiled by that awesome --link option! :)
