I'm a rule follower by nature but I think some people are going a little overboard here.
If I was Mr. Orange I'd file a NASA report, learn my lesson (which he already has stated he has done), and forget about it.
Because he busted a bravo for a minute by a few hundred feet over a congested area departing a uncontrolled field doesn't mean he needs to reread the AIM, go for more training, and most likely won't need to show a proactive attitude to the scary FAA inspector.
He did the smart thing by filing the report and covering himself. Now just sin no more
