They're hardly wasted, since there's not an enormous shortage of situations where dual wielding is impractical or downright hazardous, as well as the aforementioned 'needs multiple people' thing. Waste would be if I took DIF on an item that can't use its maneuvers due to lack of equipment.
Also, you're not complaining about inability to use feats, you're complaining about not being able to use feats that conflict with your desire to be an item incapable of independent movement. Why would you even HAVE those feats, IC?
