You don't have to see it...you have a choice of having it if you like it, whereas I don't because I live in a state that loves to turn gimmicks into requirements. In my opinion, there are more than a few things that can increase the chances of ND when a mag has to be inserted in some of my guns and not others for disassembly procedures to begin. I don't like mag disconnects for that reason mostly, but not exclusively. But lucky me...I am forced to have them now.
