DPS display could easily be solved with a system already in game.

Um it would let you know how much dps you are personally doing on a fight. You could test yourself on a dummy and improve your rotations based on that number. You could improve your strategy on a given fight adn do more dps. It would absolutely be valuable to know your own dps.

Then obviously if you are in an FC/ perma group you would share those numbers with your fc mates, who arn't going to kick you out of a group because of a number.

So my solution keeps people from being harassed, and gives you all the info you need.

I suspect you want to see everyones so you can kick people out of groups.

A) Those who are willing to parse themselves on a dummy already are

B) As others have stated, if there is no metric to compare yourself to how do you know if you need to improve?
