commands is the default title?

Yes.
In previous revision, the 81L self.parser._positionals.title was set to Commands, force argparse displays "Commands:" as title instead of "Positional Arguments:". But it can be done by setting subparsers title to "commands", as same as other venv/self/cache subparsers, without touching the internal members.
