Decent read - it further helped me appreciate the position from which Python 2 devs require certain non-trivial, non-ported libs are coming.
That said, as a mostly Python 3 developer, PEP 404, to which he links, provides much insight and justification for ending at 2.7. In brief, the changes all seem to me to be efforts to make Python more 'Pythonic' (i.e. TOOWTDI).
