Why does it need to be able to delete contacts & calendars:

- See, edit, download, and permanently delete your contacts

- See, edit, share, and permanently delete all the calendars you can access using Google Calendar

So, I am a bit paranoid, but I bet some on HN will enable this for their corporate calendars. If I were a government-sponsored entity or small organization I would definitely spend a few grand on designers & engineering to create a product like a calendar or a shiny new email client to learn some trade secrets. Just saying... why hack your way into a corp when you can ask nicely to walk in the front door.
