This will be a harsh reply.

A separate section will make it better, actually. By removing the golfing from SOPW and Meditations, we are indicating that, just like obfus, we do not consider golf'ed code to be production code. It is a game, nothing more, nothing less. And, if absolutely necessary, we could post a notice saying "This is for the golfing game. Use in production code at your own risk." (Personally, I think that notice should be at the top of the Obfu section, assuming your concerns are crrect.)

As for golfing being a premature optimization ... I have no idea where you get that idea. Golf is a game. It's kind of like speed chess - you don't play it in standard tournaments, but it's neat to play in the park.
