I don't think this is urgent, but it might be better to land the basic
structure first and improve it gradually I think? I would be happy to
continue working for the improvements as I don't plan to leave it as
just the initial version.

I worked on the v5 review notes, but if we are going to consider
designing a different API, then it doesn't make much sense to send a v6
patch before finishing the design, which requires additional people in
the topic. That would also mean some of the ongoing review discussion
would be wasted.
