No, you're right. I also assume a Fixes tag to be sufficient these days
and any version comment to be more of a hint for humans.

Indeed, and that would also catch things like dependencies and other
commits that eventually end up in the stable trees. This could also be
automated based on the

that gets added to the commit message during backporting.
