Hmm. I honestly never knew about it. I can see how it could have some practical advantages, albeit only a few. For example: It might make it easier to get to surprise spots in SnD early. However, considering the USAS fires party streamers and overkill would restrict you to using only one weapon (unless you actually use the USAS...), the cons outweigh the pros.
