> since there's an elaborate explanation (not that it's needed)

Clearly the explanationn is needed. Most of us didn't understand what you meant. After grasping what you're asking for, I get your request, and I think it'd be nice if Apple implemented this for you and others, but I don't think iOS is broken, nor would I enable such an option if it were implemented – it wouldn't solve a problem for me.

You might try to understand that you are in a minority in wanting this, and that the current behavior is actually acceptable for the vast majority of iPhone users.
