I'm a bit wary of this, but it really does seem like a decent model for most things in the App store. It's pretty clear there needs to be some exception mechanism, since Xcode and Lion won't run in a sandbox, but there were already restrictions. TextWrangler in particular removed some functionality in its App store version. And things like TeXLive and the Haskell Platform and most other developer tools never appeared in the app store.
