From what I've seen the "Fixes" tag is typically used by people who
are backporting patches, e.g. the -stable folks, to help decide what
they need to backport.

Fixes: tags say what commit introduced the code being fixed, whether
it manifests in a real problem or not.

It has nothing directly to do with -stable and exists in it's own right
whether a change gets backported to -stable or not.
