If the whole fight can be scored a draw, then it is logical that the round can be scored a draw. That rule has not been repealed.
I wish more 1st and 2nd rounds were scored 10-10. There is no reason why uneventful 1st rounds that are won on 2 jabs landing should count the same as a dominating round. Canelo-GGG fights should not be decided on 1st rounds that didn't impact the fight.
