You can reuse the backing compression nut, or cut the copper back if there is room.
They also have sleeve pullers that will slide that nut off.
It's in the kitchen cabinet, so not a big deal either way.
We carry double stops on the truck with two handles. I don't like a single handle with two outlets.
In that case, I just solder on more pipe and make it two stops.
I've yet to find a supplier that carries the two handle stops in 1/4 turns. I would love to have those.
