I didn't say that.  NumPy has exactly the same issues.  You proposed
to tie newer versions of 3rd party modules to newer Python releases.
I think it's wise to stay at least 1 or 2 releases behind.  You don't
want to lose your users because you forced them into a bad upgrade of
the rest of their Python installation.
