[TYPO3-english] Typo3 6.0.0: Protected getters in BackendConfigurationManager ...?!

[B. Kausch]

Hi!

Why are the most getters in the extbase class 
BackendConfigurationManager protected? I wanted to use the 
getCurrentPageId method to get the current page ID in my backend 
module controller.

First: Is there a reason why this method is protected?
Second: Is there another Way to retrieve the page ID in a clean 
API way?
