Some of us like to test Python code against as many versions as possible. 
It's bad enough to have to maintain locally patched versions of a few 
Python-related ports just to expand the version lists, without having the 
Python versions themselves disappear.

My own philosophy is never to drop anything without a sound technical 
reason, rather than just being "too old".  If the same zeal for 
eliminating Python versions were applied to OS versions, MacPorts wouldn't 
run on anything older than 10.12.

Checking port dependents is inadequate, since it doesn't cover 
"dependents" based on user interest.  If one were to remove all ports 
without dependents, and iterate, there would be no ports at all. :-)
