Fair point, yet, for example, I don't use the standard calculator. I use an RPN calculator app that emulates the HP41 calculator. I have to unlock the phone to use it. Same with the clock. I use a different clock app.
Anyhow, the point I think remains: The user ought to be able to choose what's on each side of that wall.
