Fair enough. Would you then change all commands that change option values so
that they too tell Customize that the value has been customized? Would you
somehow make sure that not only commands but all Lisp code does the same
thing?

If not, then the problem you raise remains for every option other than a
minor-mode variable. No - it remains even for a minor-mode variable, except
when it is toggled via its mode command.

What is special about toggling a minor mode in this respect? Why is it an
exception? That is the question.

Making a minor-mode toggle command do this does not take care of the general
issue you raise, in any case. And if a user is really worried about the
scenario you raise, then s?he can use `customize-rogue' instead of
`customize-customized' in the hook.
