My bad, I probably should have said "easily available" rather than

This is true.

There are none in particular, I just wanted to test the water and see
what the status on this issue was. The ticket posted was merely the
catalyst for enquiry. If the benefits of the new features aren't
considered enough to warrant a change then I'm happy for us to stick
with 2.3. I'd like to hear where other people stand on this issue and
perhaps see what criteria would be sufficient to require an update in
the required python version. Thanks for your input on this Robert.
