History or not, any suspension would be pathetic. It wasn't a dirty move during a basketball play where somebody could get hurt. That's what suspensions are for. This was a scuffle. We see scuffles in the NBA (of varying severity) every month.
It wasn't even a KG elbow to the face after the play. It was a player getting in another player's face after the play. Definitely a fine, arguably an ejection, if it's a suspension the league is weaker than ever. Players react in the heat of the moment and emotions come out. As long as nobody is trying to start a fight (ie punches) I don't think it's a huge deal.
