Considering time is such a factor, that's more of a reason NOT to have a mercy rule. Pressed for time, someone is far more likely to blunder. Sure, almost nobody is coming back from -10 but 1 in 500 might, due to the nature of the match.
Also, you're forgetting that people have the right to play for a stalemate if they choose, that shouldn't change just because you're too slow.
The very nature of the format is to think faster. If you run out of time, they played better than you.
