OK, next option is
directions=1 (way)
directions=2
directions=unknown.
That way, the key has no built-in value itself forcing the value to be
read to have any, well, value !
And someone reading that tag will have no idea what it stands for. Maybe
those are different exits? Does it has something to do with lanes?
Oneway makes it very easy for every mapper to see the tag and know what
it means. Another benefit is it's very simple english word.
