For JB, the READ_EXTERNAL_STORAGE permission is not enforced by default.  It may be enforced by default in future releases. Developers have the option of enabling enforcement to test their application and some may begin to include this permission on applications.  To avoid user confusion, the permission is placed in the development tools group.
