It seems to me that for a long time now stable releases haven't been trying very hard to follow the stated policy [1], in particular the parts that say
> It must fix a real bug that bothers people (not a, "This could be a problem..." type thing).
and
> It must fix a problem that causes a build error ([...]), an oops, a hang, data corruption, a real security issue, or some "oh, that’s not good" issue. In short, something critical.
