I vaguely remember that one of the arguments against replays in the stadium was the fear of enraging the crowd, potentially leading to trouble. You see a, I don't know, Chelsea player lash out and kick your star forward right in his recently injured knee (totally hypothetical, of course) and...
It is 100% true that the challenge system is much better suited to the NFL because, as you say, it's stop-start already, being broken down into discrete "plays", and, more importantly, it has a stop clock. So time spent on a challenge doesn't change the game clock.
Another thought on offsides. I suspect the original intention of the rule wasn't to be measuring toenails to see if they are just past the last defenders ass cheek. The idea was to prevent deliberate goal hanging which would cause games to degenerate into a game of super long balls to the guy...
