Well you have a chance of a draw if you could shuffle your king and hit the clock faster than your opponent. Like you, I think such competitions should be confined to bullet chess on the ICC and elsewhere.
If the idea that flag fall in the final period of play ends the game regardless were to catch hold, I would propose for a three hour game that the move rate be 90 moves in 90 minutes followed by adjudication That way you know how to allocate your time and you win or draw if you can reach 90 moves with a decent position.
I've also found actual 10.2s pretty rare. Implied 10.2s are more frequent - that is where players accept or offer draws because 10.2 existed and <2 minutes was approaching.
50-move rule. Or three-fold repetition
Can't be proved - no scoring. In any case you might run out of time well before 50
