Those assertions assume that:

* operating systems have stable releases every few months; and

* they have a zero-length process to get a stable release of Python into
  the stable OS release; and

* the user is always running the latest stable OS version immediately
  after its release.

When, in reality, the OS team will need quite a long time to ensure the
stable Python release works smoothly with all of the rest of the OS; the
stable release will come some number of months after that assurance
process is complete; and the user will upgrade some wildly varying time
after the stable OS release is complete.

That reality means “any decent OS will have Python 3.4 today” rather
bold, only a month after its release, and eliminates just about all OSen
from “decent” category.

On the other hand, you might have meant “Python 3.4 is available *for*
any decent OS today”; this is a very different thing from the OS having
that version of Python.
