Looking at release and useful bugfix support dates in:

	https://devguide.python.org/versions/

We are still on Python 3.9 which went EoL last October, so with Python 3.13 
bugfix support ending this October, and each release until 3.16 each following 
October until 2029 (presumably Python 3 Eol?)/
Should we be trying to get updated more frequently, like maybe even releases 
every two years, while they still have bugfix support, and have mot dropped to 
security fixes only?
Also about how many updates are actively applied during legacy security support?
Or is my thinking about these releases wrong in some way?
