Vancian magic is called Vancian magic because no one else does it that way. It's fairly singular. On the other hand, people born with magical aptitude on account of some sort of spirit bloodline, or people who wrest or cajole their supernatural powers from otherworldly entities, are pretty standard and not associated with any authors in particular. Unless this is some sort of shadow at-will/per-encounter/per-day powers argument, about which I have no particular opinion, because it seems easy enough to graft daily limitations on at-will/per-encounter powers if you really think you have to; and besides, the 4E wizard looks like it's stepping away from the Vancian thing, so may as well talk about spellcasting fluff.
