Absolutely not. This argument could be made, with a great deal more
justification, against the changes to remove recovery.conf, and I'm sure
quite a few other changes that we've made between major versions over
the years, but to do so would be to hamstring our ability to make
progress and to improve PG.
We don't guarantee this kind of compatibility between major versions.
Those users have years to address these kinds of changes, that's why we
have back-branches and support major versions for 5 years.
Thanks,
Stephen
