Wow, that's shocking. I've only ever used GApps for (2), but I just kind of assumed that deleting a user didn't also auto-delete their data in the organization's GApps account.

Perhaps I was being overly simplistic. Presumably folks that set up their own GApps account for their domain understand that they're setting up a different kind of Google account. The disparity is always jarring, though, esp. in the case of Google Plus.
