Most people will probably play the game with add-ons, but if all you want to do is roll up a fighter or a magic-user and bop some goblins on the nose for an hour or so, I think the game will have to support that, too, and not in some dark corner of forgotten rulespeak about all the stuff you have to take out, but right out the gate, because someone who wants that kind of game isn't going to go through the time to mod something more complex to their liking.
Ah! Now there is a point I agree with you on. The new player, or the casual player, might want something very simple to start with.
