I knew about it. But - I never needed it and I always scroll over it
when I show --help in my trainings.
When I was young - some when in last century - I learned that you never
should remove a feature without pre-announcing it as deprecated.
I think it is better to mark it deprecated in 9.2 and totally remove it
in 9.3.
