Same comment as https://github.com/htmlhint/HTMLHint/issues/1202#issuecomment-1283484433 I think it makes sense, but dropping supported versions is usually a semver major change, so it needs a version bump. It would probably be the time to include the other breaking change in https://github.com/htmlhint/HTMLHint/pull/728
