proto3 deprecated the "required". This should be a tag only, wouldn't have any side effects, right? 🤔

[dconeybe]

I don't know what effects it has, to be honest. But it is definitely different from proto2's "required" keyword. You can just assume it's correct since it's used elsewhere in the protos.

CodeLab said it should generate java files when compile protos: https://g3doc.corp.google.com/codelab/protocolbuffers/g3doc/java.md?cl=head#compiler-output:~:text=with%20the%20option%20java_multiple_files%20%3D%20true%2C%20the%20compiler%20generates%20a%20.java%20file%20for%20each%20message%20in%20each%20.

That is because the Android build system will compile the .proto files into .java files at build time. Our TypeScript build setup does not have that feature. Therefore, we need to compile the protos manually and check them into source control.
