> There is a reason Apple does what it does (supposedly to match a real keyboard)
This argument doesn't stand since the shift key itself changes when you press it (it switches from an empty arrow to a filled arrow), something a real keyboard obviously doesn't do.
There's just no practical nor logical reason for the iOS keyboard to act like that.
Shift key or Caps Lock key? The caps lock on a keyboard does have visual feedback - usually in the form of a light above the keyboard (so it's not obscured by your hands), though my favourite keyboard had a light on the cap lock key itself. Shift, being a transitory key, is not active if there's no pressure on it.
