I have a found a few packages that are "linked" (e.g. they have dependencies on either the Python27 or Python2/Python meta-package), which would explain this to some degree. Usually, it's just a rebuild (e.g. a re-configure) of the depending-ee...

by default "python" is "python2" so anything calling python still 
requires python2, see:

https://www.python.org/dev/peps/pep-0394/

and there are a lot of packages in cygwin doing it.

Packaging requires time and currently on python we are short of it.

I am moving to package all python-subpackages for 3.8 and
after we can look to move some packages from python2 (2.7)
to python 3 (target 3.8)
