For the Match/MatchSuccess and MatchAll/MatchAllSuccess case, you also define
case, can you also define a 3rd message type to for the renderer to send to the
browser to Ack receipt of the Success message. I think we need an akc to
transfer ownership of the blobhandles embedded in these messages (so the browser
knows it can drop the handles its got open for them).

That's reasonable, but right now we intend to add blobs to Responses on a
downstream CL rather than this one, there's a TODO in the content side of this
to that effect. Should we add a TODO somewhere in here?
