Yeah, please update to v1 from RFC because I'm looking at this and wondering
where v1, v2 was and why I didn't see them...

Generally I'd also advise un-RFC'ing a biiiig series IDEALLY be done early in a
merge window :)

We've pretty much shut the door to new series this cycle, but being so late in
the window at -rc5 would mean no way for this one anyway.

But in general it's going to be a rebase pain this, and I'd rather not see it
land in mm-unstable at this point, because that's supposed to be 'what's in the
next release' and it's stuff like this that leads to 'I am not sure what
mm-unstable represents any more' being a thing.

I think in an ideal world we'd ONLY see this in mm-new.

I wonder if we need some process for un-RFC'ing really, where somebody kinda
asks rather than it being a vibes thing as it is now (or a 'people don't reply
to my RFC' which yes I'm guilty of :)

Anyway this is more general points and not about you Usama, because - hey - all
this stuff is pretty unclear generally.
