This seems to me just one example of a set of additional components we might expect the working group to come up with, which in my mind is a good reason to make it a working group document.

Yes, an interesting idea.  It should be easy to design an EDNS option

request a different client-timeout) and (2) indicate whether some RRs
are stale and perhaps how much stale they are.
