But nobody wants that because it breaks compatibility.

I don't care about when it's not needed.  I only care about when it's
needed.  AFAIK people have started talking about this POSIX -- because they
wanted to add a -- in cases where it was needed (the original examples were
`tla add -- file' and `tla file-diff -- file').

If -- is not needed, then we don't need POSIX --, right?

I don't want to follow the POSIX spec.  I just think it would be good for
people to be able to use a POSIX-style -- when needed, and I'm saying that
this can be added without conflicting with current uses of --.

The specs, yes.  The uses, no.
