Right on. Regardless of all the bletching over functionality, I'd be more concerned if you lost your focus on getting the basics right.
Having said that, it would be nice if someone could document (however roughly) the changes at each iteration. I know this goes against what you said in 'Arc's Out'[1] but I think it would help folks in fixing up their existing code and encourage the Arc community to dive in deeper... and that, I would have thought, can only be a good thing.
