Performance regression from using `email.message.Message.get_params()` as replacement of `cgi.parse_header` following PEP 594

Personally, I’d strongly prefer not to revert this change, since relying on the Python stdlib whenever possible improves maintainability, reduces potential security risks, and benefits from broader community scrutiny.

This might provide a false sense of security in the case of code that isn’t being used or maintained by anyone else^[1].

If Django is the main project that relies on the performance of this code, you might be the only ones who notice when it regresses.
