This is common pain from the Bazel community as well. IMO rules_proto should stop exercising the "build protoc from source" codepath, as that's only intended for C++ projects per https://github.com/protocolbuffers/protobuf#protobuf-compiler-installation

If you want to use the github main version at HEAD, or you need to modify protobuf code, or you are using C++, it's recommended to build your own protoc binary from source.

I can make that change if the maintainers indicate a willingness to accept it.
