As such I don't see a problem backpatching commit 1362bc33e02 as it
appears to be a localised change.

I agree with this line of reasoning here or in general as well but
personally I am a bit hesitant to back patch changes which are not

backpatching the part of code you want to backpatch, so I leave it to
your judgement.
