Here's something to start the fight ;-) ...

1) What would you do with class methods that you cannot do with
   e.g. globals and functions ?

2) How would you determine which methods are class-only methods and
   which are one usable by instances ?

3) If you don't like globals (see 1), wouldn't it be possible to
   store the state you want to manipulate using class methods
   in some other context object ?

My impression is that class methods are not really needed and
would only make optimizing Python harder... but that's maybe just 
me ;-)
