Parts of this discussion seem to have become confused. There are comments about external views and there are comments about rear-, left- and right-views.
1) EXTERNAL view is seeing your own ship, from the outside. How that is done is IMHO irrelevant, be it simulated drone, external camera or magic spell.
It's purpose, again, IMO, is to enjoy looking at your own beautiful (or battle scarred?) ship, either to enjoy the view, or perhaps to inspect damage. I don't think it has any further practical purpose.
2) REAR-VIEW (and left and right views) as seen in the original, are ways of looking around space from INSIDE your ship.
With the new cockpit and game features, left and right view are apparently no longer necessary, as one can turn one's head (although personally, I would prefer three monitors with fixed forward, left and right views respectively). Of course, one can now also look 'upwards' - in my multiple monitor set-up, I'd need a fourth monitor on the ceiling
A rear-view 'mirror' or camera could be handy for docking, or perhaps in combat, but this is at least partly covered by the scanner. I suppose a miniature projected image of the view out the back of the ship would look nice, but where would you have it? There's already so much to look at.
Anyway, I don't think FD will fail to supply us with what we need, and also a lot of what we want.
