No, it'd just reduce the surface area a bit. People on less-than-
the-latest-minor-release would still have the issue. In any case
back-patching further than v14 would be a nonstarter, because we
didn't remove protocol v2 support till then.
However, the analogy to "\d commands might fail against a newer
server" reduces my level of concern quite a lot: it's hard to
draw much of a line separating that kind of issue from "inline
COPY CSV will fail against a newer server". It's not like such
failures won't be obvious and fairly easy to diagnose.
