At the very least, they should give the connecting gate number, and if possible instructions to get there and to walk to the gate. I presume they don't do this since the gates are subject to change, so printing this up front could mislead someone. To me, I shouldn't really need a physical boarding pass. They should just be able to scan an ID and inform me the gate number during boarding.
