TypeScript supports checking for "unused locals", which actually includes locals, private fields, private methods, etc. If a private thing is actually needed as part of the API surface, you can change it to public to resolve the error. This seems like a good check to have, as it highlights unused bits of code that perhaps got lost while refactoring. This changes our config to reject them and fixes up a few existing cases.
