It is just an unnecessary dependency I noticed, nothing more. I was not aware of the issue with try except block and I get that comparing the python version would be unnecessarily complicated. Thank you and feel free to close this issue.

Thank you for differentiating typing vs. collections.abc and typing vs. typing_extensions! I just now realized you meant to prioretize typing_extension.Literal over typing.Literal - I was thinking about the opposite. Similar to numpy, pandas(-stubs) requires 3.8+.

I think we should simply wait until pandas requires a newer python version before avoiding the typing_extension imports.
