You've missed the point of my comment entirely and pulled two items out of context.

You seem to ignore the fact that people ignore ux advices. You can ask them politely, but they'll still slap something together and call it a day. And there's no way a complex control that you described can get into popular ui libs. Or to be approved by all "designers". These default looks of type="radio" and type="checkbox" are the last stand. If you break it, you'll complain even more but nobody would listen still. Cause defaults and easy ways rule the world. Accessibility is a rough battle already even without ideas that definitely won't work.

I disagree with every paragraph. Too long to address every line.

If you had better points than, it doesn’t matter, idea is “old”, and/or people can’t learn, well you made them poorly.
