I don't think we want to support having another flag for a dialect, since that will result in more problems down the road. We already have a problem with the number of configurations we support and adding style-guide configurations won't help that. IMO this should just be a clang-tidy check. They can be enforced just as well as compiler warnings/errors, and don't cause problems for other people.
