Python 3.8 is expected to include PEP 594 "Removing dead batteries from the standard library"... one of the modules schedules to be deprecated is cgi.

As out of date as the module is, reading the PEP made me nostalgic for the days of hammering out a quick CGI script, and I've probably got a few of those scripts still chugging away.
