Looks like new versions of bazel do things differently, so I need to burn some time updating things
although, it looks like I can stop having my own fork of this mess: https://github.com/fireduck64/rules_protobuf Bazel rules for building protocol buffers and gRPC services (java, c++, go, ...)
and it looks like it might unscrew some nonsense I had in channels, where I couldn't add the dependency right
and of course the new stuff needs a new version of bazel
