Sure. What I meant, however, was something analogous to what `setq' does for `defvar' and `defcustom'. Something, for instance, that a user can put in .emacs to override a predefined `defface'. Yes, I realize that users can use Customize, but I'm thinking of something less interactive. As another example, I just sent a message to the list about a buff-menu.el patch. In order for others to try it out, I need to tell people to explicitly use `C-M-x' on a particular `defface' sexp. This is because buff-menu.el is preloaded, it calls `defface', and the patch gives a different definition of one of the faces. It would be simpler to give people a snippet of code to load (not eval with `C-M-x'), to override the predefined `defface'.
