Maybe it's worth mentioning that support in the actual remote helpers
will be added in a subsequent patch.

This makes sense, but there doesn't seem to be any code in this patch
that implements this.

Why is process_connect_service() falling back to stateless_connect if
connect doesn't work? I don't think this fallback would work, as a
client that needs "connect" might need its full capabilities.
