[TYPO3-mvc] [Best practice] VH arguments?

[Tim Schoch | GSTALTIG]

@core devs: I wanted to ask this question for some time, so here it is:
In some VH you use initializeArguments and in other you add as argument to the render() method.
 
Is there a reason in which case the one or other is the better one?
I personally would prefer to have them in initializeArguments as it makes extending core VHs less tedious.
And even more secure as my code won´t break when you add another argument to it.
