I find very logical for ships so far in the future to have mounted cameras around, especially big ones. Drones solution feels like "we don't want external cameras but we will make the worst option to stop this arguement".
It's nice to see the parts of the ship moving, the reflections of the sun on the metal surface as you drift through the rocks of a ring, watch your trails (and surely understand how your ship behaves), watch a planet disapear while on supercruise, etc. that is more immersive for me than plain cockpit (that is why the immersion breaking has no value, it's totally personal).
Anyways, this 3d person external view has been here around a lot, still this says something.
