Next to code readability, there's IMO one could reason to properly support this would be a clean and easy way to get proper help strings for such options.

Of course I can do something like:
parser = argparse.ArgumentParser()
parser.add_argument("--foo", nargs="+", help="Mae govannen", metavar=("bar", "baz"))
args = parser.parse_args()

and later check that, say, only 2 arguments are allowed.

But the help text will be an ugly:
>$ python3 --help
>usage: [-h] [--foo bar [baz ...]]
>optional arguments:
>  -h, --help           show this help message and exit
>  --foo bar [baz ...]  Mae govannen

indicating that >1 options were allowed.
