PEP 594 ("Removing dead batteries from the standard library") deprecated the following 19 modules in Python 3.11 (or before) and their removal in Python 3.13:

• aifc
• audioop
• cgi
• cgitb
• chunk
• crypt
• imghdr
• mailcap
• msilib
• nis
• nntplib
• ossaudiodev
• pipes
• sndhdr
• spwd
• sunau
• telnetlib
• uu
• xdrlib

I propose to remove them as soon as possible in the Python 3.13 development cycle to help users to prepare for this incompatible change before Python 3.13 final release (scheduled for October 2024).

I plan to work on pull requests to remove these modules.
