No, by that logic, we should not change any behavior in a back-branch
upon which a customer is plausibly relying. No one relies on a certain
query causing a server crash, for example, or a cache lookup failure,
so fixing those things can only help people. But there is no reason at
all why someone shouldn't be relying on this very old and
long-established behavior not to change in a minor release.
One reason they might do that is because there was a discussion about
what I believe to this exact same case 4 years ago in which you and I
both endorsed the position you are now claiming is so unreasonable
that nobody will mind if we change it in a minor release.
So you now think this should be back-patched when previously you
didn't even think it was be good enough for master.
