There is no consensus yet. Besides https://pypi.org/project/idna/ we could also consider to wrap libidn2 and ship it. Both PyPI idna and libidn2 have potential licensing issues. I don't like the idea to reinvent the wheel and implement our own idna2008 codec. It's not a trivial task.

Once Python has a working idna2008 encoder, we need to address integration into socket, ssl, http, and asyncio module.
