totally agree.

An interface to a class (or its concept, anyway) is there for a reason. 
And you should adhere to. I may also say that if you need to access a 
protected, or private for what is worth, member of a (library...) class, 
then you should revise your code... because either you're using the 
wrong class, or your problem can be solved in a different, possibly more 
elegant, and surely more OO compliant way ;-)
