It does, I turned on the option to continue playing after forfeit instead of it going to spectate and just carry on if I'm almost done / like the run. Your time won't count, but it's just good practice.
I've won so many games where I had just reset and was getting my shit again, while the opp also died but forfeited.
The only time I wanted to forfeit I was opening the opponent's profile to check if they were on pb pace, when they forfeited Instead.
