But this isn't editing.  AFAIU, Customize creates a
'custom-set-variables' section from internal Lisp data structures,
while distinguishing changes done by the user from other kinds of
changes, like those done by original ~/.emacs settings.

I don't think it's that simple, see above; but I might be wrong.

IANAL, sorry.  I hope someone else will be able to answer that.
