The documentation for smtpd (https://docs.python.org/3/library/smtpd.html) states that " smtpd should be considered deprecated" and recommends aiosmtpd.

Are we planning to remove it from the stdlib? Note that at the moment the smtpd module doesn't emit deprecation warnings, and aiosmtpd is not part of the stdlib.

This came up on https://bugs.python.org/issue28533, where we were hoping to be able to move the (properly) deprecated asyncore and asynhat to test.support (because there are still a few tests that use them). It seems that smtpd is that last blocker for that.
