If I'm reviewing that patch, do I tell the author they have to be consistent and revert other changes? etc.

I've had a go at expanding it. Please let me know if you have other suggestions.

The latter. Given that the code doesn't keep to the existing .clang-tidy rules I'm not optimistic that we could persuade code owners to start now. That's not to say it couldn't happen eventually, but my aim at this point in time is to make it easier to use good variable names and I don't want perfect to be the enemy of better.
