I agree that the deprecation process should have been followed better.  
However, I'm not sure what you mean by them being faster than their 
Pyhton counterparts.  Both functions in nxutils are replaced by 
functions in _path.cpp, which are also written in C++ but are more 
complete and don't have broken corner cases.  They may be slightly 
slower  because they have a few more checks and handle Bezier curves, 
but they are not significantly slower.
