The kernel begrudgingly admitted of the existence of LTS releases, they really don't like long-lived kernels and people not tracking at or near the latest release.

I dunno, if you think about it for more than a few seconds you can see the obvious holes in it, like it's definitely true that some bugs are "may allow RCE", but you also can do a LOT better than not even trying. And even if you do say "we're not putting the effort in to backport security fixes" (which is fine), that doesn't entail "security bugs are just bugs".

These are smart people. If it wasn't about their own project I really think they'd have a different point of view. I wonder what they say about Microsoft's security bugs for example!
