Did our pet UI just get removed?

[Zethix]

So I see that it is still in game, but apparently it was meant to be removed?
- someone please tell me what magic trick I can use to command my pet while casting a spell?

For some reason clicking the pet UI allowed me to command the pet while casting (very usefull for mezzing while telling my pet to back off), my own hotkeys did not offer the same luxury, same with typing /who is doable while casting, but its not possible to click a /who macro, am I missing something?
