I think it's an unintended side-effect of language design - 
setters/getters everywhere, variables are evil, use them only locally.

Unintended like, 'protected' means visible to subclasses, noone ever 
mentioned superclass.
So, superclass is treated just as any other class.
I don't think there's any security issue specific to superclass.
