I didn't have an opinion about this change behavior. Maybe Noah can comment on
it. Until we have an agreement that this is a regression, there is no fix plan.
Regarding v14, it will be supported for another year [1]. If the regression was
applied to old stable branches, it should be fixed as well. Sometimes, we need
a totally different patch for back branches. There are cases that the
regression is not triggered in old branches and the committer decides it is not
worth to apply it. Sometimes the fix is invasive (for example, require other
commits to be backported) and the bug is rare that we leave it alone.

In summary, stable branches usually don't change the behavior (unless we
consider the behavior totally broken).
