This isn't anything like a rule change.    A dead stone is only a concept 
based on what will happen in the future IF the attacker plays correctly.

If the attacker doesn't play correctly,  the stone will not die.   But of 
course you would prefer to award the win anyway without finding out, no 
matter how weak the players are.

Of course it will happen, if the second player is stupid enough to stop 
defending himself.    I really don't see the point.   Whether you have the 
protocol or not,  a player can play out the game to the bitter end in the 
hopes that the opponent will screw up, perhaps filling in his own eyes. 

The protocol makes it possible for COOPERATING programs to pass early.    You 
can never FORCE a non-cooperating program to pass early, so it's really no 
use constructing scenario's where a game will get played out to the end 
needlessly due to some flaw in the protocol.

But only to a point.   The greater good dictates that we maintain some 
reasonable expectations too.   GTP itself raises the standard and yet it has 
probably prevented some entrants from participating.   But it does enable us 
to have these interesting tournaments.
