You can put a comment there explaining the situation. Ideally we=E2=80=99d have per-output propagation, so one could put polkit-gobject in one output and polkit-agent in another and have different propagated inputs. But that=E2=80=99s not supported ATM, and may= be not widely useful. Ludo=E2=80=99.
