Yeah I considered adding a test but wasn't sure how to frame it. The real source of truth for pass options are the parsing functions, and there isn't a great way to extract all possible options from these as they are all structured a little differently. I suppose you could catch old options that don't exist any more by just testing every option, but it wouldn't help with new missing options, which seemed to be the main problem. I agree it would be a bigger change needed to declare them more systematically.
