Just to allay your fears on one point. IDTTL has never awarded 10 points to any team because the opposing team has defaulted. ALL matches HAVE to be played. The only let off is if the match does not effect promotion / relegation and playing is virtually impossible, in which case neither team gets any points.
Thus if a team falls foul of the new scheme, they would get 5 points deducted, and have to score at least 5 points when the match is played to avoid 'losing' points. The opposing team would still score as though it was a normal match.
