I agree with this scan idea. It would make sense, but for me it comes from a dev standpoint too! We could take SS of the other persons ship, say "THIS is whats overpowered against my setup" or something similar. More data given to us, helps us plan bettter. =)
It's a good suggestion that should be implemented at one point, but right now I think a lot of effort should go to just extending game play time and making interaction with the game as comfortable and bug free as possible.
In the future I hope they do mining and salvaging so I think sensor scans with details like this would probably enhance the activity too.
