I also think that going to Experimental might be a good idea, for the
following two reasons:

Reason 1: without some kind of standard it is hard to use cache
digests on the public internet, since it is hard to negotiate which
draft version should be used. Note that a cache-digest frame is
typically included in the first flight.

Reason 2: even if browsers do not support cache-digests, a variant
(using HTTP headers) can be implemented using ServiceWorkers. Having a
standard format defined as an RFC would help us gain interoperability
between implementations using ServiceWorkers.
