We don't know yet what will happen and when. And it may well be that this methods are not suiteable for what we will do then and we have to deprecate them as well.
It may well be that we just use JSession as the wrapper and include Symfony or whatever transparent for the extension. There is no need to add a wrapper around the wrapper :smiley: 

Static functions aren't evil by itself. There are perfectly fine useages of those.
