AFAIK anonymous faces work fine in font-lock. They can be a bit more
delicate to us because many places that accept faces also accept lists
(either of faces or of other things) but in general there's no real
restriction that I know of.
So I think the "do not accept" part is not true (any more?), but it's
still the case that you're generally better off using named faces
when possible.
