Now in the first Beta, it's built in.
Do you plan to stay with it?
I'm just asking to know if 3rd Party Developers can use it for there Modifications, because if you plan to remove it until gold, we would know that we shouldn't use it, or put the needed zf classes in our own add-on packages.
It wouldn't be nice, to have now many Add-ons built on Xenforo & ZF Framework, which wouldn't work with feature Versions of XenForo were ZF have been removed.
