Yes.

So the user can be in full control. RMS knows the feeling.

The user wants a piece of code that he can stick into his .emacs,

The user wants to put it into a file that only he is editing.

OK, good. then have the snippet be a set-face-attribute snippet.

The documentation would be: "Here is a snippet you can paste into your
.emacs file manually, if you don't feel comfortable allowing the robot
maintain your customizations."
