Not sure why I’d want to define a language independent interchange format in a language specific way and remove all of the tooling help at the same time. Why is this better? A why section/motivations would help greatly.
There is an explanation in the README file, but I'll explain:
It helps to standardize workflows across a number of different source repositories (all Go based), where a number of different developers had come up with different ad-hoc ways of generating code against protobuf definitions. Since the syntax is Go-derived, it reduces cognitive load for developers when specifying protocol buffer definitions. We understand that it may not be for everyone, but it works for our team.
