I think IDLs and gRPC in particular are a meaningful advancement in the problem space. The ecosystem and productivity that they enable via programatic tooling were really eye-opening for me (The OpenAPI ecosystem is, imo, extremely poor). They also have better support for modern techniques like streaming and even load-balanced streaming.

Amen, brother! gRPC is the best thing since sliced bread. Typed APIs are just so nice to work with, and OpenAPI is very unsatisfactory.
