I really don't see the aversion to an outside camera viewpoint. I've played lots of good (and vastly more realistic) military sims that have included external cams. In fact, I can't actually think of one that doesn't include it. If it doesn't seem out of place in a WW2 subsim, can't imagine it would hurt the gameplay of a space trading game.
Watching your ship maneuvering and being able to take screen caps, videos, etc. of your actions adds to the enjoyment of the game. Doesn't have to include over-the-shoulder with usable HUD if peeps are all uptight about some pvp perspective advantage. Third person camera pics and recordings are a big part of free advertising the community typically takes part in rather happily.
Ah well... competition will be dictating very soon.
