The challenge will be in defining the user data model with the correct amount of detail and granularity such that capability requests are meaningful. Also, there will always be lazy users. For example, on the Outlook app for iOS - when attaching a picture to an email from your Photos - you can provide permission for the Outlook app to see just the pictures you select, all pictures, or deny permission completely. Awesome - but how many just share everything? How many users really look at the permissions requested by the Android apps they install? But it does make anything that goes wrong completely the user's fault, though.
