It seems like Android has three choices 1. The current approach (which made it possible for the wallpaper app to steal user data from millions of users) 2. Prevent apps from accessing data such as voicemail-password, web-browsing history etc. (but it is possible that some apps may have a legitimate reason to do this and blocking these apps may not be fully consistent with the open platform goals) 3. Throw a big warning message EVERY time an app tries to access sensitive data (or perhaps for the first 10 times and the first 10 days...). It is a compromise solution, but users may find this annoying. Either way, this is a somewhat tough problem.
