Maybe we should consider finally having that discussion once the governance model is chosen and before we consider adding a new module as things like people's inability to access PyPI come up pretty consistently (e.g. I know Paul Moore also brings this up regularly).

I don't think it's asymmetric. People have raised several practical problems with a large stdlib in this thread. These include:
- The evelopment of stdlib modules slows to the rate of the Python release schedule.
- stdlib modules become a permanent maintenance burden to CPython core developers.
- The blessed status of stdlib modules means that users might use a substandard stdlib modules when a better thirdparty alternative exists.
