Loss forgiven on DC

I know this has always been a talked about subject and is very difficult to manage. However, I personally just went through a game with 2 people that NEVER connected to our game. It ended in 13 minutes. I think in situations like this, why wouldn't there be a loss forgiven awarded? If someone NEVER connects to the game, everyone that is connected (and loses) should get a loss forgiven and the person that never connected should lose the amount of LP that you would if you left during champ select (because it's essentially the same thing).

This way you don't need to know if someone left or just dc or whatever because it doesn't matter. They're still punished and the people who are trying to play don't lose 30lp on a game where they lose their first inhib at 7 minutes. I'm just curious as to why this hasn't been implemented as there are literally now disadvantages or any ways that it could be abused, at least from my perspective. Maybe even limit the winning team to getting >10LP (or the amount the afk lost) as they got a "free win". If you're gonna punish a team because they can't play a fair game, why are you rewarding the other team because they did equally nothing to deserve a win?
