While a solution is likely possible here I'd like for us to notice how
two features have gone now under our nose for Xen on v4.0 which have
issues. Proactive maintainer reviews would detect these issues but we
can't bet on these, and testing is just as reactive and slow. I'm
hinting we keep our eyes out for an architectural solution that would
avoid these issues. Don't ask me what that is just yet...
