I think we shouldn't standardize it.  If one wants to write a small
POSIX system from scratch, aiming minimalism, this flag is absolutely
useless, having the better 2>/dev/null which is useful for every
command.

As a user, I also think it's easier to read the code with 2>/dev/null,
since I don't need to read any documentation to check what flag X to
command Y means.

For systems that already have that flag, it's useful to keep it working
for scripts that already exist, but we don't need to standardize it for
that.


Have a lovely day!
Alex
