gh-144484: Warn users not to use wsgiref in production

[sethmlarson]

Follow-up from the precautionary CVE for wsgiref, where even though the module is documented as a reference implementation (instead of production-ready), there isn't any explicit docs for this like other modules with this property (eg: http.server).

• Issue: Document that wsgiref is not meant for production #144484

LGTM.

https://docs.python.org/dev/library/http.server.html has a similar banner but it also has a "Security considerations" section.

Sorry, @sethmlarson, I could not cleanly backport this to 3.13 due to a conflict.

Aha, it seems like you should backport the change manually to 3.14.

Aha, it seems like you should backport the change manually to 3.14.

The bot got confused, backports have already been merged #144511 / #144512.

Should this not be treated as a security fix and backported all the way?

[sethmlarson]

@StanFromIreland I believe it should be handled as a security-related change.
