I thought that was the consensus from the v2 comments anyway. If I end up doing a v4 for this I can just include the removal as a 2nd patch (without a fixes tag) and Alex can squash or keep separate as preferred -- if not you can feel free to do that removal with your cdev follow-up that exploits this work. Thanks, Matt
