Policies

Q: Should developers do it themselves? Or ask another dev to do it to keep some review sanity?

A: It depends: preferably a developer should be able to backport him/herself but

• do not break the release branch
• make tests
• only fix bugs, do not introduce new features

If the latter is unclear, it should be discussed on the developers list. If in doubt, ask! In this case, a path/diff is appreciated.
