Doesnt RPC means nothing? Some will say GraphQL (others will hate it), some will say gRPC (same), others will say JSON-RPC, others will just bring back SOAP to life.
RPC is likely a synonym to "single endpoint for multiple handlers" but without a format (JSON in EE for ex to stay consistent) and a transport it is undefined and hard to integrate (as were remote EJB between services when not the same vendor and version).
So on EE side the one making the most sense is likely JSON-RPC since it will enable to be interoperable and optimized but guess it can start a lot of debates we should maybe avoid to work on a stronger and lighter platform instead?
