posts in those sections are just as game for criticism as any other section. I'd say maybe more so.

I'm a bit surprised you think so, and I'm not sure whether I agree... despite there of course not really being a way to measure that. I've usually felt that the criticism in SoPW tends to be harsher for the reasons I named above. But perhaps one of my original suggestions of posting the code as an RFC in Meditations is the best - in any case, my main point of not posting code like that in SoPW still stands.
