No idea, how this move could be labeled philosophy, since it is going to 
break nearly every 3rd party python software out there. In the end it 
only contributes to arch users isolation as it will always take arch 
specific patches to get legacy code working. No sane distribution will 
follow this pattern. 

I'm really sorry to have answered to this thread without understanding 
the full scope, and therefore even contributed to the confusion.

As a consequence, I'm going to ignore each and every arch linux python 
compatibility issue, that may arise here.

Thanks for the warning,
