I do not. I'm still of the opinion that we ought to back-patch
pg_surgery. This didn't attract a consensus before, and it's hard to
dispute that it's a new feature in what would be a back branch. But
it's unclear to me how users are otherwise supposed to recover from
some of the bugs that are or have been present in those back branches.
I'm not sure that I see the logic in telling people we'll try to
prevent them from getting hosed in the future but if they're already
hosed they can wait for v14 to fix it. They can't wait that long, and
a dump-and-restore cycle is awfully painful.
