Huh? `face-spec-set' is user-visible, but it is also definitely part of the Custom interface[1] despite the name. It is definitely not capable of flexibly manipulating XEmacs specifier-based faces. Arbitrarily moving it out of the Custom code and into faces.el doesn't make it any less a servant of the Custom machinery. (The reason I insist on this is that it is part of the Custom interface that I am going to have to jump through hoops to preserve in making Custom specifier-aware.) I would guess that the reason it is the recommended interface in Gnus is to keep people from using (real) face specifiers in a way that Custom (and FSF Emacs) don't understand. (Unfortunately, that currently includes any use of non-ISO-8859-1[2] fonts, as Custom doesn't deal with them at all.) If Custom is going to be protected from destroying people's faces, alternative entry points to the Custom implementation should be protected in the same way. In any case, people are going to be just as unhappy if `face-spec-set' permanently resets all their backgrounds to White and their kanji fonts to Illegible as they are when `custom-set-face' does it. This is a good place to do the surgery in question (special-casing the 'default face).
