+1 on not replacing Fixes: tag with some other name, as there might be
automation (not just at SUSE) relying on it.
As a compromise, we can use something else to convey the "maintainers
really don't recommend a stable backport", that Sasha can add to his filter.
Perhaps counter-intuitively, but it could even look like this:
Cc: stable@vger.kernel.org # not recommended at all by maintainer
