`[default: ]` vs. `(default: )`
Is there a reason why default values of user options are sometimes displayed inside brackets [] (3 occurrences):

but most often inside parentheses () (6 occurrences):

See also https://github.com/pypa/distutils/issues/251, since class Command is defined in distutils.
All this lives in setputools now. This is just a CLI tool. Feel free to ask there, it might be easier to unify now that it's all in one spot.
