Debian testing is pretty much a -stable tree, see the git log history:

https://salsa.debian.org/kernel-team/linux/commits/sid

It follows a current stable tree, and moves on to the next one once it's
available (about a week after Linus releases a new kernel).

Fedora's rawhide is just (daily?) builds of Linus's tree, they don't
care what stage the tree is in at any point.


My point is that no one picks a release and sticks with it more than a
week. If someone plans to use a release for longer term they use a
-stable tree, and if they are interested in testing, they move on to the
next release once it's available.

There's no one, for example, who picked up vanilla v4.16 and plans to
keep using it for a year.

This leads to my point about rushing fixes: -stable releases for v4.16 are
done weekly, there's no need to rush them in during v4.16-rc8 just to
make some imaginary release no one will pick up.
