This is partly true...it is true that the loss holds less weight over time, however once the forfeit is awarded it is used in calculating your rank no differently than if it had always been a loss. The only difference would be if there was a transient effect in how you selected the opponents you played during the period where the forfeit was not yet recorded. If you played identical opponents and got identical results in the meantime your rank would be identical whether the loss was immediate or the forfeit was delayed.
Well, there are differences in a couple of ways:
1.) In some cases, you would not play identical opponents, but stronger opponents. Playing stronger opponents helps you to improve, so there is benefit to it. It's not that uncommon of a story that someone makes a new account on KGS because their rank is stuck.
2.) This assumes that you eventually get a win. You never get the win in some cases (actually, I've had a handful of escapers, but I don't recall ever having received credit for a forfeit - it's possible that I've missed one, but I'm sure there are others in a similar situation). If I play 100 escapers, who each escaped 3 times and then quit KGS, there are 100 wins that I should have that I never get credit for.
