I hear that. I don't have a strong opinion about whether serving stale data in general is desirable or abhorrent. However, the pragmatist in me says that people are already implementing things like this anyway, and a standard approach is better for all concerned than a fragmented set of uncomfortably-different implementations, which will surely make troubleshooting problems harder.

I also think if a standard specification can be obtained it ought to include appropriate instrumentation to allow a response to indicate whether data is stale or not. 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.

I support adoption with all of that in mind.
