The thinking around a similar (but more mature) project, tRPC is interesting around this. They're very clear about the fact that it's designed for tightly coupled typescript web app monorepos. I believe the creator even was talking about the name not being ideal, but it might be too late to change. Aside from maybe being able to generate an OpenAPI spec (something that the tRPC community is working on), it's just going to fall apart outside of web apps. But for those developers it's great for eliminating this weird step where we need to think about all our data going into a completely unstructured string (json) when going between our server and client. For most full stack JS/TS apps that's all you need.
