Buf Connect or any RPC design really is great. I'm sick of REST too. No more endless discussions about how to make this endpoint the most RESTful or how to cram a feature into REST that doesn't fit. "Oh you need an endpoint to hibernate the server? Just POST a new Hibernate object to the /api/v2/hibernations service."
No. With RPC we can just make a HibernateServer call and be done with it.
