Wrong. The ":" carries information.  For example, if we have:
  
    [global] 
    script-entry-points = 
        somescript = testpath.to:some.function

we can easily generate an oldstyle setup.py from it:

    setup(entry_points={'somescript': 'testpath.to:some.function'}, ...)

without having to load live objects.  The dotted name does
not allow that and thus carries less information.
