What's the point of even sending this? What am I supposed to do with
this? The series is at v12. We should aim at converging to merge at
maybe v3 or v5 or so, at the latest. There are legitimate cases where v1
or v2 are RFC-like, figuring out the direction etc., but the goal for
every single version after that should be that it's the last.

BR,
Jani.
