Nice theory, but in practice there is a big difference, because in most
cases the "changes outside customize" either always take place or never take
place, so it's a rare occurrence when the problem you mention shows up.

And even if it does show up, taking a look at the customize buffer when you
see the problem will tell you "changed outside customize" warning you of
the problem.

What is the problem you are trying to solve, really?
I.e. in what way is the message "changed outside customize" a problem?
