I used b73198a47ffe in Fixes because that commit introduced the problem with the temporal tuner. I thought a Fixes tag could also point to a commit that is still in a maintainer tree. The tip handbook describes that for tip [1], though mm may handle it differently. The hash can still change in mm-unstable, so the tag may need updating. I also found this reply from Andrew [2]. He says he tracks these fixes by filename and folds them into the original patch before moving it to non-rebasing git. Maybe squashing is indeed simpler here, also for backports. So either option is fine with me. I'll leave that to you and Andrew.
