Based on this thread, there is some willingness to provide Python 3.9 support for this library.

As much as we'd like to migrate to Python 3.10+, it's difficult to migrate enterprise codebases before official EOL status.

I'm curious what the process would be for making such a change? I'm assuming there's more work beyond just putting up a PR with 3.9 compatible code.

Happy to assist in this effort if necessary.
