Even more to the point, it was an extremely major change and would take
a huge amount of QA effort to ensure that dropping it into v13 wouldn't
cause fresh problems. The PG community has exactly no interest in making
such effort.
Besides which, what do you imagine "depends on v13" actually means?
If you have an app that works on v13 but not v14, maybe it's because
it depends on the old behavior in some way.
Spend your effort on updating your app, instead.
