…efaults (pythonGH-155191) Parameters with a default value which are not in any group were always required in the generated argument parsing code, although they were rendered as optional in the signature. They can now be omitted, and ambiguous combinations of optional groups and parameters with a default value are rejected.

Parameters with a default value which are not in any group were always
required in the generated argument parsing code, although they were
rendered as optional in the signature. They can now be omitted, and
ambiguous combinations of optional groups and parameters with a default
value are rejected.
