Something related that I've been thinking about is that there aren't many popular data storage systems out there that use HTTP/3 and/or gRPC for the lower latency. I don't just mean object storage, but database servers too.
Recently I benchmarked the latency to some popular RPC, cache, and DB platforms and was shocked at how high the latency was. Every still talks about 1 ms as the latency floor, when it should be the ceiling.
Yeah QUIC would probably be a good protocol for such a system. Roundtrips are also expensive, ideally your client library would probably cache as much data as the local disk can hold.
