In WER at least, the options for entering match results for team sealed are 1-0, 1-1 and 0-1. I'm not certain what the options are for DCIR, but I would imagine that there is a similar principle. In my experience, players still often fill out slips as they do for individual matches, so seeing 2-1s etc. are common.

I would not bother doing this, especially at a GP sized event - it is such a lot of effort for such small gain, as it doesn't affect the result entry and if the slip has come in before the end of the round, has no impact on the tournament. That said, I would ensure that judges go around all outstanding matches some arbitrary amount of time before the round ends (say, 10 minutes) and make sure that there is not already one team that has one two of the matches in that match! Because if those are just playing the third for fun at that point, that genuinely could delay things.
Regards one team member not showing up: I agree that the rest of the team should be allowed to finish that round with a loss in his match, as technically the No-Show team member is not dropped until the end of the round. However, at the end of the round, him being dropped means that the whole team should be dropped - a team must consist of three people.
