Being able to surrender in a game with one or more AFKs

Why is there no function to be able to forfeit a game that has multiple AFKs? I have had multiple instances where there are two or even three AFKs and the other team instead of pushing mid and ending decides to be incredibly toxic and BM the team with the AFKs making the game last at least 20 min. I understand there must obviously be reasons why you can not surrender until 20 minutes but PLEASE add a function to be able to surrender a game when you have an AFK in the first five to fifteen minutes of the game.

If you have the argument that well what if the AFK comes back and you could potentially win? Well if the other four or three players don't want to keep dragging the inevitable out why can't they just surrender? Even if the AFK comes back he deserves the loss because of his negative behavior.

I have just been appalled by the toxicity of the other team when there are AFKs on one side. Allowing for an option to surrender early would remove that element and allow both parties to simply move on to another game. This would reduce toxicity and minimize the unpleasantness of the whole experience.

I really want to see the communities opinions on this topic and want to hear your thoughts, good or bad.
