No. Punishment is used to act as a deterrent, so that this - or anything else like this - will never happen again.
Can't tell if you're being sarcastic or not, but rarely does punishment work as a deterrent for anything but children. And often, that's a 50/50 proposition. Adults tend know the consequences and the potential punishments, and make their choice based on the risk/reward.
And this will likely happen again. Probably not on this scale to a program with this much prestige. But someone at some university, will cover up heinous acts again eventually. It's virtually inevitable.
SMU got the death penalty, it hasn't stopped programs from cheating, it just forced them to get better at it.
