Part of the design philosophy is giving the game back to the hobbyist gamer.

The hobbyist house rule spirit is it's thing, if you're willing to put in the time to make it yours.
Thanks for bringing that up - I view Swords & Wizardry not just as a set of the 0e game rules, but also as a project to enable two things; free-form open ended gaming on one hand, and super-tinkering with the rules on the other. Both of those are characteristic of the 0e mindset "back in the day," but nowadays there's not a complete overlap at the S&W boards. Some free-form S&W gamers look with dismay at the elaborate house rules of the tinkerers.
