Depends on how easy it is to get a cable from the node to the Joey, or the tech can also install a tap on the cable for the Hopper and use that if it's easier.
If the homeowner is happy with a coax coming out of the wall rather than a wall plate. I expect most are.
I hardly ever use a wall plate unless requested, we have plugs that go over them before adding connectors that fit snug into the hole as long as it wasn't opened up too much to allow it to slip back out. These plugs look fine so long as you keep them low vs right in the middle of a wall. The less barrels in a line the better and that is what a wall plate will add is a unneeded barrel.
