will we consider removing signature_stub when simulating?

[dsawali]

good point, removed.

[hui-an-yang]

surprised to see PreapplyReponse here, but understand if it's returning the same object

[dsawali]

PreapplyResponse is basically just content so I guess it was just reusing the type. It was the same for run_operation so I just followed suit.
