This is one of those ideas which is completely the opposite of the way I want to do things, but which will probably gain enough traction that I'll be forced to accommodate it after several years of frustration, grumbling, and workarounds.
I can see that perspective, but I don't think that will happen. Companies jump at any chance to steal each others customers, so the necessity threshold has to be very high for something like this to be adopted across the board.
