Right, but what seems to have been the case during the net.git
(and linux-stable.git) triage so far is that user impact matters.
A configuration that works by coincidence and not by intention, but
otherwise works reliably, still works, at the end of the day.

If you read the weekly net.git pull requests sent to Linus Torvalds,
you'll see that maintainers try to make a summary of what had to be
changed and why. There isn't really a strong reason why this patch *has*
to be in those pull requests. That's kind of the mindset of what makes
"stable" "stable".
