I concur nntplib should be left alone. There are possibly even less used
network protocols such as telnet (tenetlib) which are not targeted by this
PEP but could have been by following the same logic. FTP is another one
that despite no longer popular, still has a constant user base (you?d be
surprised by the amount of traffic we got over FTP in the last company I
worked for). Overall, I think the bar for a module removal should be set
very high, especially for ?standard? things such as these network
protocols, that despite being old are not likely to change. That means that
also the maintenance burden for python-dev will be low or close to none
after all.

It seems to me also spwd/crypt modules fall into this category (all UNIX
platforms have the shadow password db, which is nice to have in python out
of the box). In that case the removal appears to be more justified by the
security implications than them being not widely used though, so I would
use more caution and treat them differently (eg. opt for doc warning +
investigate a possible replacement). Also note that spwd could be used to
parse /etc/passwd, despite I admit its primary use case is password
checking. Certain users may even not care about the additional security
provided by PAM (eg. internal devop scripts).
