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.
