WB-50 - Why get rid of SlideConnect?

I'm just curious - I picked up some WB-50 wall bracket and noticed the Series II got rid of the slide-connect feature that made wiring so much easier - no having to deal with the wire fitting behind the speaker etc. Why the change? 

 

The description on the Bose website still says "It features an integral connector to simplify the process of connecting the speakers..." but that is not the case, much to my surprise when they arrived.
