The question is what is a penalty - You will with this change in every case loose not even one point but can win a lot of points, so I think it is no penalty.

The other question is how it is in other teamsports ?
What if in soccer one team would come only with 9 player instead of 11 - You think they would tell the other team who has 11 player that they should take out 2 player and the match will be played with 9 against 9 player ?

Or in other sports like tennis, table tennis or chess where the team-events consist (mainly) from a addition of the single-results what will be happen if one of the teams will come with less player than they need - I think it is clear that they loose the matches where they have no player for - so I think it is not natural that you just cannot show up and get a draw (0:0) - IMO this is a design error, always it should be a match and if there is no match because one of the player don't show than the other win the point.
