Opinionated, maybe (although it seems to me most rules are reasoned and a justification is given).
But something practical has to be specific.
It has happened time and again to come across something it appeared to me as an arbitrary an unnecessary rule, but with more experience I think it's better to have some "debatable" specific rules that something "open to interpretation", especially if many people will have to work on the same codebase.
