I don't know of anyone.
Due to the weight of the winch it would make it harder to get anyone to take it along.
I know of a couple people that keep a 12V winch in their truck.
Then again, it is incredibly frowned upon to ever ride off trail by yourself. That is an open invitation to disaster.
Wingnut rides an Apex and even with the weight of that machine the 2 of us have never been in a position we couldn't get it out. We do carry a small block and tackle just in case though.
