Apparently after 7 years they decided it can't be fixed and updated the docs.
I'm baffled with the resolution of this bug. Removing the docs doesn't help anybody.
In my experience, argparse.REMAINDER works reasonably well, and apparently I'm not alone; there's >100 packages in Debian that use it:

There has been an open bug for this for many years.
