Compare mypy-protobuf to protobuf --pyi_out support (starting with 3.20)

[gitpushdashf]

Has anyone compared this with mypy-protobuf's output? I'm not sure if it supports grpc or not.

I haven't done a comparison. You're welcome to!

grpc_tools still does not support protobuf 3.20

grpc_tools still does not support protobuf 3.20

Is this true? It seemed to be working for me.

I do see that it doesn't support v4 or later, however:

i cant use --pyi_out with python -m grpcio_tools.protoc

[gitpushdashf]

Hmm. This looks related: grpc/grpc#29650

It doesn't seem production ready yet. mypy gives a bunch of errors running on the --pyi_out generated stubs

[nipunn1313]

this project has spent a bunt of time battle hardening the type stubs and adding tests.
AFAICT, the built-in --pyi_out stubs have not. Your mileage may vary.

Might be a nice idea to use the test suites from mypy-protobuf on the built in stubs and see if it uncovers bugs.
