But only if a later suitable (for everything dependent on it) version is possible on every supported OS. And it would mean bumping portfiles, and rebuilding everything depending on dropped versions.  It probably wouldn't be worth the bother, and given all the constraints, might only get rid of a few versions.

This ;-) nasty ;-) piece of bash scripting will give an oversigt of all
the pyXY-{name} ports and which versions of python they claim to support

I'll post a file on my website, when it has finished running :-)
Finished : https://macports.mathiesen.info/portfiles/python/pyPorts.txt

Optimised/revised script ; runs 9 times faster than the original

--- begin bash script ---
#!/macports/bin/bash

declare -a pyVersions=( 26 27 32 33 34 35 36 37 )
declare -a pyPorts=( $( port -q search --name py- \
                     | sed -E -e '/^py-/!d' ) )

maxLetters=$( \
    for (( i=0 ; i<${#pyPorts[@]} ; i++ ))
    do
        echo ${#pyPorts[${i}]}
    done | sort -u -n | tail -1 )
(( maxLetters+=5 ))

for pyPort in ${pyPorts[@]}
do
    printf "%-${maxLetters}s" ${pyPort}
    subPorts=$( port info --subports --maintainer ${pyPort} )
    for V in ${pyVersions[@]}
    do
        subCount=$( echo "${subPorts}" | fgrep -c "${V}" )
        if [[ "${subCount}" -eq 0 ]]
        then
            echo -n "   "
        else
            echo -n "${V} "
        fi
    done
    echo $( echo ${subPorts} \
         | sed -E -e 's/^.*://' -e 's/.* ([^ ]*\@[^ ,]*).*$/\1/'  )
