I don't think we can rely on everyone to have 3.9, 3.8
is not EOL yet, and we do want to still test in distros with
older compilers that may also come with old python.

It should just work with a regular optional argument instead
of the BooleanOptionalAction (without the --no-validate flag):

This bit may have to become 'if not self.validate',
since the flag in this case is None rather than equal
to False. This also improves readability.
