Hi Brian,

python3-requests for the time being will pull python36-requests.

That is fine for your
   #!/usr/bin/python3.6m

Cygport has hard coded the OBSOLETES, this is something
we need to change in cygport:

 >>> python36-requests OBSOLETES: python3-requests

rebuilding from your source I had

units requires: cygwin findutils libreadline7 python38 python38-requests

It seems the "inherit python3" is pulling the current choice
of my system

$ alternatives --display python3
python3 - status is auto.
  link currently points to /usr/bin/python3.8
/usr/bin/python3.7 - priority 37
/usr/bin/python3.6 - priority 36
/usr/bin/python3.8 - priority 38
Current `best' version is /usr/bin/python3.8.
