No, there should be no expectation that Python 2.x interfaces be  
preserved in Python 3.x unless they have demonstrated utility.  
Furthermore, there should be no expectation that a particular  
interface survive for more than a few major Python versions. PEP-004  
describes how deprecations are expected to proceed at module  
granularity.

Any argument along what you call "philosophical" grounds will not be  
successful. Technical (including aesthetic, convenience, etc.)  
arguments *may* be successful.
