I'm slightly back, so it's time to get the oar out ;)
I think there are two problems
1. It takes a lot of time to identify the stability fixes you need so
simply doesn't fit the release cycle.
2. You often need them in the unstable release to work out if they are
the right solution.
We have several "stable-ish" trees of 3.x.y format.

A look at some of the bug data shows that is all too true, and also that
despite the NSA fiasco and the like we have an awful lot of open,
probably real hits in coverity and the like which are effectively widely
available to the bad guys to analyse too.

That ought to be happening every release. Every maintainer should be
asking "is my tree full of shit that needs cleaning up" and prioritising
it, including pushing back on developers to find a good balance between
fixing and new stuff.

It would be a good time as you went towards it to ask "what code is
buggy, problematic and simply not being maintained", and chuck it. It's
in the git history so if someone cares in the future they can ressurect
it but the tree has a lot of crap in it that slows down other work and
simply doesn't matter to anyone. (and if it does them rm -rf is a great
way to create new maintainers)
It might be very instructive to find the set of devices and archs that are
- not looking maintained
- not shipped by any vendor anyone has ever heard of
- or shipped by every vendor but no users show up in their collected data
