Should this be backported to 3.12? |

No, we don't backport deprecations. |

No, we shouldn't introduce new deprecation warnings in patch releases. Lots of projects use |

These are undocumented, private functions, but there's unfortunately widespread usage of them in third-party libraries. Even if we provide a new public API for people to use in Python 3.14, it will take a while for third-party libraries to migrate to the new API. In the meantime, they may get incorrect behaviour if they fail to pass in a value to the type_params parameter. So let's warn them about that.
