So could we not standardize a protocol for this that both sheepdog and

The protocol already exists, nbd. It doesn't support snapshotting etc.
but we could extend it.
But IMO what's needed is a plugin API for the block layer.
What would it buy us, apart from more downstreams and having to maintain
a stable API and ABI?
Currently if someone wants to add a new block format, they have to
upstream it and wait for a new qemu to be released. With a plugin API,
they can add a new block format to an existing, supported qemu.
Hiding block drivers somewhere else doesn't make
them stop existing, they just might not be properly integrated, but
rather hacked in to fit that limited stable API.
They would hack it to fit the current API, and hack the API in qemu.git
to fit their requirements for the next release.
