I don't think it's acceptable to simply remove the functionality.
If you wanted to argue about swapping the meanings of STDIN and -
(as defined by the patch) then we could debate about which way is
more consistent and whether it's worth breaking backwards compatibility
to improve consistency.  I could probably be talked into supporting
that; as you say, we've done that before.  But taking out a useful
behavior that has been there a long time, simply because you've decided
it's unintuitive, is not okay.
