why are passthrough_args before the mode parameter? that would bury the mode
parameter pretty far down the command line (trying to avoid another runtest.py
CLI fiasco :D).

Suggestions are welcome - I think the reason is these arguments are defined in
the main parser as opposed to each of the subparsers, since they're common to
all subparsers.
