Part of what we're arguing in this article is that there is no good answer today because of the assumption that TCP was good enough. Homa is challenging that assumption (as many others have tried before). My view is that if you want something better than TCP for RPC today, QUIC is the best thing available, as discussed here: https://systemsapproach.substack.com/p/quic-is-not-a-tcp-rep...
What you run over that for your RPC is a matter of taste - gRPC is certainly popular, and can be run over QUIC.
