The STO (or Cryptic Engine Devs?) also seemed to think it shouldn't be in their game. Maybe it's for the better. It would certainly seriously change the entire game balance if they changed it now.
Cannon Scatter Volley, Torpedo Spread, Eject Warp Plasma, Gravity Well, Tyken's Rift, Photonic Shockwave, Charged Particle Burst and Dampening Field are all area effects that clearly would affect everyone.
Beam Fire At Will and Scramble Sensors probably would not.
Mines are a corner case - it could be argued that Mines in Startrek have to use more elaborate sensors then today's mines and can differ friend and foe. (It could especially be argued that Starfleet wouldn't make a habit of laying mine-fields that can hurt innocents.)
