After a series of emails [1], TdR (OpenBSD) convinced GvR (Python) to improve security inside Python. That led to two PEP (Python Enhancement Proposals):

• PEP 504 ‘Using the System RNG by default’
• PEP 506 ‘Adding A Secrets Module To The Standard Library’.

Credit to Theo de Raadt is explicitly given in PEP 504 Acknowledgements and PEP 506 Rationale.
