Wasn't the volume key snapshot feature in Camera+ done as an undocumented easter egg? Apple's developer guidelines at the time clearly stated that you have to list all hidden features upon submitting the app for review. I believe you had to visit an URL in Mobile Safari to activate the feature. It was also well understood that you couldn't alter the functionality of the hardware controls.

I'm inclined to think that a physical camera button is not something Apple couldn't come up on its own. Just like wi-fi sync, it was listed as a missing feature on quite a few review. That said, the matter naturally becomes quite different if they still disallow 3rd party developers access to the volume rocker.

It's disappointing to see that Wired is repeating the wi-fi sync story.
