Interacting with an existing code base?

This looks like a great project, thank you!

A few questions:

1. For an existing, largely Google [grpcio](https://grpc.io/docs/languages/python/generated-code/) based codebase — how does support look like? For example, the generated code seems to _require_ `asyncio` and [grpclib](https://github.com/vmagamedov/grpclib), which would require quite some rewrite?
2. Do I understand correctly that deserializing incoming requests and serializing outgoing responses is supported already, either via data classes or Pydantic?
3. What about interceptors, in particular the [grpc-interceptor](https://github.com/d5h-foss/grpc-interceptor) package?

The issue names grpcio-generated code, asyncio, grpclib, Pydantic, and grpc-interceptor but no repository files or tests. Start by checking the linked generated-code documentation and the project's current support boundaries for serialization and interceptors. Done would be a maintainer-confirmed answer covering compatibility, serialization, and interceptor support.
