It's funny, because everybody but you seems to understand how bad an idea this is. Maybe that should make you take pause, not that it seems to have in the past when you've had crazy ideas you felt compelled to post.
Your idea creates a situation where players are incentivized to continue playing after the whistle goes, that's not the type of behaviour you want to encourage,
More cameras is not really a reasonable answer here, and it's only being proposed because you want to impose a rule change that doesn't solve an actual problem.
You seem incredibly stuck on defending this idea to the death, but it's death happened long ago, I won't keep beating the dead horse, it's one of the dumbest ideas I've seen posted here, and that's a damn high bar since there have been some doozys,
