I think I'd really enjoy flexing my creativity around such an interesting character restriction, and making a party work (both functionally and story-wise) would be a fascinating challenge for both the players and the DM.
I'm not sure if this interpretation is warranted, but this restriction also seems (to me, at least) to tend more towards a light-hearted, almost goofy (in a good way) campaign - a great Saturday afternoon diversion!
Or for a tourney.
