Hi Marco,

Here's a list:
-asn1crypto
-crypto
-cryptography
-lockfile
-openssl
-pyasn1
-pyasn1-modules

I get the choice aspect. I don't get the Debian aspect. Out of the handful of packages I am handling for my own needs, lots of the patchsets are from Fedora. Cygwin feels more "Fedora-ish" to me than it does Debian. Even the Fedora guys have picked one Python horse to ride. They even have a unversioned Python package to make "it feel" more transparent (the major version change) for end-uses, which I like:

$ lsb_release --release  --description
Description:    Fedora release 31 (Thirty One)
Release:        31

$ python -V
Python 3.7.7

$ which python
/usr/bin/python

$ rpm -qf /usr/bin/python
python-unversioned-command-3.7.7-3.fc31.noarch

I know this goes against all the PEPs, but I prefer it "When Things Just Work" out of the box. It's been very transparent for my Python usage. I think Fedora 33 will start to remove older Python versions/packages from the code/build repos, they won't be available for install.

I would like to help Cygwin but I don't have bandwidth to help with 3 or 4 generations of Python.

Oddly, out of the packages I build "test" versions for, they are Yaakov's handiwork. It's nice work and I feel at home working on/in his work. Feels very mingw-w64-ish/Fedora-ish to me, both of which I know quite well.

Thank you for picking up the work.
