In defence of TZ... It makes commanding a fleet far easier to do as it lets you see everything rather well whilst its only other use is having an easier time shooting at snubs who are flying in a straight line. As we know the crosshair doesn't compensate for any movement that isn't a straight line.
As for pvp flying larger ships requires further TZ and sometimes in close quarters the game will target the hull and miss shots rather than targeting the crosshair and so turret zoom making the crosshair larger than the hull helps remedy this as you can target part of the crosshair and the shots will still be centered. Essentially just another bug work around.
