I still doubt your claim about patching and youhaven't given any evidence,
but let's just make the assumption it's true because otherwise even trying
to hold a discussion is fruitless.
I also dispute your claim based on the backpatching claim that Linux would
be Linus' hobby if the file system guys thought this way. Given that
"stable" Linux branches often aren't, if there weren't aggregators who
provide upgrades that are at least supposedly tested and reasonably stable
and sometimes did their own back patching, Linux wouldn't have the sort of
success it does because people would have to do alot more choosing between
getting bug fix X and doing huge amounts of tests to make sure nothing
else is broken. Thus, I believe you are greatly overstating the effect
that your first claim has towards your second to the point of making an
invalid argument.
Personally, I'd in general wish that 8.0 got a fix for this because that
way we could (after sufficient testing) push an 8.0 version that we
considered stable to suggest people move to. However, I don't have a
whole lot of time to do such a patch nor to do "sufficient" testing, and
I'm not arrogant enough to believe I can order around volunteers and
companies I'm not a customer of.

My last company's experience with Oracle support still leaves me
questioning that claim. They basically got "don't do that then or move to
the newest major revision" when they had a construct which caused the
server to stop responding. It's not the same conditions (although I
believe the DBA did reload from backup because noone could guarantee that
there couldn't possibly have been dataloss), but it's certainly not
indicative of the sort of "full scale efforts" you're describing.
