So far, there is no clear agreement to expose C PyConfig structure in Python, so I close the issue.

My PEP 587 has been accepted. I chose to not expose PyConfig in Python in the PEP. But I'm open to revisit this idea later, especially to move towards PEP 432: implement multi-phase initialization (only partially supported in my PEP 587).

But I would prefer to a different rationale than exposing hash_seed. For hash_seed alone, I don't think that it's worth it. Moreover, Christian wrote:

> hash_seed and use_hash_seed could be added to sys.hash_info. This would be the first place I'd look for the information. After all I implemented it. :)
