I believe the point of using a .onion service is that you don't need
to go through an exit relay (which is a relay connecting you to non
tor services through the "normal" internet) as your service is already
directly connected to the tor network, so you can directly build a
circuit to it instead of building a circuit to an exit and then
connection to your destination.
My mental model for a .onion service is a dedicated exit allowing only
that service, I have no idea how far from reality this is :)
