There's been some discussion on this.  I'm not sure what bottom line
emerged, if any.  Do we have to improve this before it can be merged?
Or before it can be declared stable?  Or just eventually?  Unless it's
the latter: do we already know in which direction to go?

I think the current stuff is good enough and the current protocol is
not hard to support even if we have something better in the future,
i.e. a guest using the current protocol is easy to support in a
backend which also supports smarter ways of passing dirty region

Thank you for working on this!
