Well, it has and does in my D&D games. The core rule books even encourage -- not just tolerate, but encourage -- house rules to fit the table.Right, and being hit in the arm by an axe in a way that's potentially life threatening should affect your hammer wielding prowess for even longer, but it never has in D&D.
There is nothing stopping a DM from assigning damage effects to different parts of the body in D&D.
