Pro Evolution Soccer 2009 had a similar feature where quitting a match before the end resulted in an automatic forfeit being saved to the only available slot. The danger involved made comebacks from behind all the sweeter.
Virion makes a good point about Larian wanting players to embrace failure. My guess is some kind of ironman mode will being included at some point. At the same time, Larian don’t really mind players abusing their systems, so it may not be a priority. I’d put ironman mode in the “comes out with enhanced edition” pile.
