There's a draft PEP up for removing a whole slew of older packages from the standard library. Slowly, of course. Probably not until 2022, and there will be supported versions through 2026. Anyway,
here is the draft.
I am still using "cgi" and "smtpd" for tiny utilities.
smtpd actually has a replacement available in pip: aiosmtpd, but then async will start creeping into your tiny utilities, lol. The cgi module will probably also continue to exist in some form on pip.
Actually, someone will probably put both on pip with the same module name, so that backwards compatibility isn't broken as long as you pip install first.
But even for small projects, flask is probably easier to work with :p
