These kinds of calls are already wildly inconsistent between ref to ref and game to game. Goalies that are barely touched and a goal is called back. Goalies that you see are significantly interfered with are sometimes called good goals.
At least with offside goals you can reduce the number of goals being called back if you simply say any offside challenge will be played back at normal speed and if you can't tell whether a player is offside or not easily then they're considered onside. Plain and simple. I don't know why we need to bring out the magnifying glass and slow down the video to frame by frame to see if someone's skate is 'offside' by an inch or two. If that's the level of detail you need to go to for determining an offside or not, then obviously they were close enough to the line to be 'nearly onside' and that should be good enough.
