I don't see unmanaged files on a removable SD card as a problem. That's the point, the SD card is for data that can be removed and handled outside the Android operating system. I want apps to be able to write things to my SD card that will remain when I uninstall them. I can do things like save a backup of my app settings then restore on a different device. The internal storage should have restrictions on managed data because if you have untracked files that get left behind when an app is uninstalled, you may not notice and they'll just be cruft. That's where I think the restrictions should be placed, not on the SD cards.
