"Preferences" would be a silly name in Emacs, because every
customization in Emacs is about "preferences".

That's a separate issue and a separate request, though.

Exactly my point.  The easy-on-newbies interface for customization is
not to present them with (a largely empty) init file, far from that.

Why?
