I went back and forth on this a bit and choose to keep it this way since its private and only really called in once place at this point (history ui). And actually only the view one is called the modify one isn't called anywhere outside of this class. We could add the additional logic but I kind of see it as just overhead right now. Normally everything is initialized just when you create the securityManager and so these routines aren't called outside of here. I could be swayed to change it. I should atleast add a comment here also. I have it in some other places, but should add here too.
