Inspire 1 Pro camera listing

I just upgraded to version 1.3.39 and see in the default cameras listed five entries for DJI Inspire 1 Pro using various lenses. Does this mean that missions created in Mission Planner can be used on the DJI Inspire 1 Pro platform? I also see that there are two options for saving waypoint files: the usual *.txt and a new Mission JSON *.mission format. Are these updates related to each other? Or is this implemented so that you can use the Inspire 1 Pro X5 camera on an existing hexacopter?

Start by tracing where the default DJI Inspire 1 Pro camera entries and the TXT and Mission JSON save options are defined. Determine whether the camera listings, mission formats, and existing hexacopter workflows are related, then document the supported behavior or clarify the required change.
