I'm wondering how to tell stable maintainers about dependencies of
(not yet applied) patches? In practice I saw that contributors use
Fixes tag for the entire chain (for the preparatory patches + the real
fix) when it's not easy / in a nice way to rebase to have a one-patch
fix followed by refactoring, etc.
