Great to see you're ok with that direction! I'm working on that then.

Sure! We'll maintain that along the way.

Mostly this is about upstream features that won't be working with the current state of the art: enqueuing a posix cpu timer on a nohz CPU may result in it being ignored by the target due to the lack of ticking until expiration, perf events may not be round-robined, etc... I'll make sure to document all these items.
Thanks.
