Quake 1 did this, iirc. From what I remember, game studios around that time played around with different bindings, but generally stuck with keyboard only bindings by default, because mouse+keyboard was still considered an "advanced user" technique. For the most part, game makers adapted to how the users were playing (WASD) rather than setting a standard and expecting users to follow.
