They're unrelated. As others have mentioned, "--" is _extremely_

almost _all_ UNIX command like programmes which handle -* style options
honour the "--" convention. _argparse_ itself honours that convention, as
does getopt etc.
And why do UNIX programs behave this way?
Because POSIX says they should:

Aye, but POSIX says they should because POSIX formalises a lot of
existing practices so that people have a reference to let them _also_
use that practice in a consistent way.
I used to lurk on the POSIX discussion list, and the length of the
discussions around corner cases was quite wearing, even just to read.
