In my opinion, the rule does more harm than good, especially at a qualifying tournament where a DQ means a season is over. As long as a wrestler is on the scale and makes weight at the correct time, is it that big of a deal if he's working out instead of sitting in the weigh-in area doing nothing? It doesn't give an advantage to be cutting 10 minutes later than the current rule set, but hurts the product to DQ the wrestlers. I also think it cheapens a UNI conference title if they win due to an OKST wrestler being DQ'd on a technicality.
At the end of the day, having the best wrestlers in these tournaments is best for the sport. As long as they aren't doing anything malicious and make the weight at the correct time, let it go.
