Wow thats new to me. Learn something every day.
So the wire you run is it the 3 conductor red, black, white with a ground or is there some special wire for these runs? In a single box I cant see what the future use could ever be .
So are most people now not using any multi wire branch circuits for that reason in new construction?
It's part of the new code requiring neutrals at almost all switches. There are a few exceptions. Also your local may not have adopted that part of the code, so it may not be a requirement where you live.
When I worked for a residential electrical contractor about a year or so ago, with new construction we began phasing out the multi wire branch circuits with a shared neutral for anything that was required to be arc fault protected. We also began running regular 3 wire (black, red, white, ground) to switch banks. We were following the 2011 code at that time. The 2014 code now requires the entire house to be arc fault protected.

It should still say something on the label and in the instructions, it's not like everone has or wants to rewire their switch legs.

Didn't want to start a new thread for a quick question. Just bought this outlet with USB built into it. It doesn't have the normal connections. My question is do you just group all the black wires together and put a cap on them and the same for the ground and white. Thanks for any help.

Yes but the question will be the size of the box that you are putting it in. 16cubic inch size?

you could always pull out the other one and see how it's done.
