What? You wouldn't put a smartcam on a larger spy drone as a way of getting a higher sensor rating while circumventing the prohibitive drone modification rules? And you had the guts to try to make a rigger/decker build with that attitude! Shame on you.
If I were doing a paparazzi drone rigger (and actually I kind of am percolating that idea tbh) I'd consider it.
But as said upthread, existing gear/augmentations using image link is all you need for regular use. And it doesn't cost much to buy 6 sensor rating on a drone; as you've said that's normally plenty enough of a limit and when it isn't, you have pre-edge.
