Indeed. Rather than super() being deprecated, it was made easier to use 
in 3.x by being special cased during compilation. Notice the difference 
of signatures:

2.7: super(type[, object-or-type])
3.3: super([type[, object-or-type]])

"The zero argument form only works inside a class definition, as the 
compiler fills in the necessary details to correctly retrieve the class 
being defined, as well as accessing the current instance for ordinary 
methods."

This deeper integration means that it could not be completely 
reimplemented in Python ;-).
