Upon seeing that this dated back to 2.11, because I am lazy and do not assess how much the fix needs to go to older tracks when I am queuing (remember: my attention span during patch queueing is measured in minutes, as people send changes to different areas), I tend to first try to see what's the oldest maintenance track we can practically apply the patch to. It turned out that the conflict resolution to apply on maint-2.11 wasn't that painful, so I took the lazy route all the way---the real fix on the oldest, even though I do not know (because I refused to think and decide due to laziness) if a next v2.11.x release is necessary, followed by a nice-to-have warning that uses newer features on the maintenance track. That way, when we decide that the fix won't be a big deal to require a new v2.11.x, but it is nice to have in v2.13.x, we could merge the first one, without having to cherry-pick. All of the above is part of how the daily maintainer workflow goes, and there is no strong preference on my side, if the original is on the theoretically oldest (i.e. maint-2.11) or on the oldest practical (i.e. maint), as long as the conflicts are not too painful.
