My mail is about official binary Python packages for Windows and macOS.
We stick to an OpenSSL version to guarantee maximum backwards
compatibility within a minor release. OpenSSL 1.1.1 has TLS 1.3 support
and prefers TLS 1.3 over TLS 1.2. There is a small change that TLS 1.3
breaks some assumptions.
Python 2.7 works mostly fine with OpenSSL 1.1.1. There are some minor
test issues related to TLS 1.3 but nothing serious. Linux distros have
been shipping Python 2.7 with OpenSSL 1.1.1 for a while.

That topic is out of scope and has been discussed countless times.
