`parseAsRoot` analogue that returns the full command stack?

Is there a parseAsRoot analogue that returns the full command stack instead of just the last (sub)command (i.e. returns [ParsableCommand] instead of ParsableCommand)?

I need to access the root ParsableCommand instance for testing.

I know about the pending @ParentCommand for 1.6.2, but it would be nice to have a built-in way to get the whole command stack.

Thanks.
