TYPO3 Core

Current behaviour:
When you lock the access to the backend by setting 'adminOnly' => '-1', the system shows an exception message if you try to acess the login form:

"TYPO3 Backend locked: Backend and Install Tool are locked for maintenance. [BE][adminOnly] is set to "-1". More information regarding this error might be available online" (Link to http://wiki.typo3.org/Exception/CMS/1294586847)

Desired behaviour:
It would really nice if the system would also show sys_notes (if available) in addition to the above message. This would enable developers to inform the user about expected maintenance duration or other important information. Just like they are already displayed if adminOnly is set to other values than -1.
