I recently reread the ending of Morrison's run on New X-Men, the arc "Here Comes Tomorrow" , issues 151-154. I hadn't quite understood the breadth of Morrison's reinterpretation of the Phoenix Force until this reading, and it seems like none of the subsequent writers have referenced any of these elements.
In light of the Phoenix's presence in Avengers vs X-men, this seems particularly important. If Morrison's version of the Phoenix is canon, the Avengers are probably dramatically overreacting.
Have other writers referenced the New X-Men interpretation of the Phoenix Force? Has it been explicitly retconned, or just swept under the rug, or is it still canon?
Bonus points if you can point me to places where Morrison's version of the Phoenix Force may have originated. I know he loves his callbacks.
