While I agree that it would be a nice addition, within the first mini dungeon the bandits kind of function as a way to pick up your weapon type.
They have a shortsword, two-handed club, several bows and staves, daggers, a shield and I think somewhere in that dungeon you can pick up a rapier. (not to mention some hidden goodies) I find it hard to think of a playstyle that's not served by this selection of weapons.
