I think its notable though, something has got to change.
To be nearly 5lbs over weight in the 155lbs division is a joke. Honestly it shouldn't even be sanctioned. The system currently favors weight cheaters. It is a HUGE advantage and would have been a disgrace if Gregor lost tonight.
Purse forfeiture to your opponent needs to be a sliding scale and this will solve the problem overnight:
30% purse - 1lbs
40% purse - 2lbs
50% purse - 3lbs
If its >4lbs, there should not be a fight. If you win while fighting overweight, you should be excluded by contract from your next fight being a title shot.
I respect Gregor for taking it, he's been on the shelf so long he probably felt he had no choice, but things need to change.
