A few points I would however consider:
When does Python 2.x will goes end of life? From there wiki: "Python 2.x
is the status quo, The final 2.x version 2.7 release is out, with a
statement of extended support for this end-of-life release. "
Which unix platform comes with Python 2.x instead of Python 3.x?
Is it possible to have a waf version working with both Python version?
If so, how much effort would it required?
If not, when do you plan to move waf from Python 2.x to 3.x?
Best regards,

On the contrary, I'd be very surprised if 2.7.5 broke things. Python is
conservative with bug fixes that go into minor releases. If you do hit
regressions like that please do tell us about them.
Python 3.0 makes a number of backward incompatible changes -
intentionally,
and documented as such - and Samba 4 doesn't support it yet. Any versions
of Python 2 after 2.5 (which is ~5 years old at this point) should work
with Samba 4.
