In my opinion, .conj shouldn't exist.  I tried to get Konrad to take it out 
at some early point in the development of complexobject.c.  I wouldn't 
worry about breaking anything, but I'm cross-posting to the matrix-sig to 
give others a chance to shout if you'll be breaking their code.

Note: for NumPy arrays there is neither a ".conj" attribute nor a 
".conjugate()" method.  Instead there is a "conjugate(a)" function which 
will work on any number-like python object in the right manner.  There 
seemed to be agreement within the SIG that this function is what everybody 
really wanted anyway.
