I keep imagining the opposite:

I am leading my league by one win and have a better goal difference of 2 goals over my nearest rival. Last game, players took red cards, now I will lose next game for sure. The crap thing is, other team will score tons of goals, because my goalie has red card. Because we don't use FIFA rules like rest of the world, I can't have a proper 3-0 forfeit, so I'm gonna lose my League too this season with BS goal difference!
Then, I would be behind you.

It's not fair to ask another team to "lose harder" so a fit team gets even more advantage. That one team gets a 3-0 technical win while others get 9-0 is what we call "luck of the draw".
