Are you saying that you edit the custom-set-faces sexp in your .emacs
yourself?

If so, then presumably you don't need Customize or use Customize to save
anything. In that case, you can keep on editing everything, including
custom-set-faces, in your .emacs. A proposal that Customize not save stuff
to .emacs will not affect you if you don't use Customize.
