A backported package was removed from the resolution process

One or multiple backported packages from newer Python version were removed.

Issue description

A backported package was removed from the application stack. Backported packages are packages that bring features introduced in newer Python versions (Python standard library) to an older Python release. These packages should be often installed conditionally by using a proper environment marker (e.g. importlib-metadata; python_version < 3.8 for importlib-metadata package).
