question about mvc in XenForo


in memoriam 1991-2020
In a word, no. XenForo has its own system for pretty much everything, only loosely based on Zend Framework.

Zend Framework 1.

Any particular reason why this is important?
ZendFramework 2 uses a different coding style that is drastically different (namespaces) and refactored / rewrote a lot of things if I remember correctly.
