asyncio (PyPI backport)

The `asyncio` package on PyPI (version 4.0.0) is a deprecated backport of the `asyncio` module, which has been part of Python's standard library since Python 3.4. This PyPI distribution is no longer needed and serves primarily to prevent accidental installation of outdated backports. Users should *not* install this package and instead rely on the built-in `asyncio` module provided by their Python installation.
