I'm not to fond of having a Protected folder that you must not put your protected method in that is confusing. I have no problem with a folder for the ObjectAttributes.ctl because you don't want to move that around. Maybe an other name for the folder, but then again the ObjectAttributes.ctl are protected. I don't know.
When you create methods it should not be possible to use the Method Location option in the Create Method dialog (if the flat structure is selected), it should be grayed out or something.
