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

Could you or someone else advise on next steps?

You can open an issue, but I would advise you keep your backport of cgi.parse_header() if it gives you the performance you’re after.

@nessita

keeping the Python stdlib offers better maintainability

I know how that might look like that from the outside, but cgi and the other modules we deprecated were due to low usage and low maintenance help (i.e. no core dev ownership).
