Nope, I've used that as a house rule since about 5 days after getting my 3.0 books. Plus, when the splatbooks came out they also got the shotput. I mean, what makes it an Orcish shotput or Orcish double-axe if they have to spend a feat to take it like everyone else. The way I look at it, spending a feat on an exotic weapon like and Orcish double-axe, or Dwarven Waraxe represents time and training in something foreign and not easy to train. Dwarves teach other Dwarves how to us Waraxe's readily, and thus they have it as if it were a martial weapon. If some human wants to try it out, he's going to have to spend some time trying to find Dwarves that can give him some pointers on it, and try to practice it on his own; thus it costs a feat.
