The archd protocol by in large draws directly from the
libarch/archive.h protocol which already has `revision_type'
(answering "is a cached revision available?") and `get_cached' (which
retrieves a cached rev if one is available).
If you're thinking about archd servers which can compute cachedrevs on
demand, I think that that winds up looking to clients as though every
revision is already cachereved. build_revision heuristics will have
to (eventually) be per-archive tunable to cope with that.
