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. > > -- > Cheers, > > David Cheers, Lorenzo
