There are currently two issues with TLS 1.3 in Python. The issue https://bugs.python.org/issue37440 can be worked around easily with a custom SSLContext. This issue is a bigger problem because there is no possible workaround.

The bug is going to break applications that verify clients with a certificate but accept untrusted server certificates. It's not a common scenario, but I just happen to run into this issue for a project at work.

I'm sorry for the mess. :( I noticed the bug a couple of days ago. It took me a while to understand the root cause.
