Expected results: Dragging the mouse pointer should have the same behavior as using your fingers on a mobile device. Ideally, the cursor should be changed to indicate your in touch mode.

Thanks for filing! The touch simulation in RDM today does "work", but it's quite basic. It sends touch events based on some mouse events, but that's it. I believe the issues you mention are the same as bug 1282089 (gestures) and bug 1271728 (show circle cursor). Since you focused on the gesture part, I'll dupe this to bug 1282089.
