If the consolidation weren't here, I'd absolutely ask for= it. This is new feature enabling. Yeah, it happens to be tagged for stable, bu= t at the end of the day, it's new feature enabling. And it's standard operation procedure to do cleanups and dedup code as part of new feature enabling. If anything patch 6 should be patch 1, but that's a minor detail I can sort= out when applying (assuming another version isn't required).
