Hi,

I am the maintainer of the above mentioned project. I was planning to implement a patch for this. But I asked OP to report the issue here anyway since I do not believe this is the intended behavior. 

For context, the issue is occurring when using the `ssl.create_default_context` function and not by manually adding the verify flag. For this, the default (in my opinion) should be to ignore any invalid certificates. Even the comment in the relevent code (https://github.com/python/cpython/blob/84975146a7ce64f1d50dcec8311b7f7188a5c962/Lib/ssl.py#L772-L774) seem to agree with my sentiment. 

I ask that you please reconsider your stance on this issue. Thanks
