After thinking a bit, I'm inclined to agree that we should move it
to "Incompatibilities". It is a core server change (third-party
extensions don't have a choice to opt out, as per postgis' issue),
and even if it's trivial, we have some even-more-trivial issues
listed there, like command tag changes.
