There's no 'plan' for this. Adding such a hint to the enum would be
pretty easy, of course. Note that these hints are currently not used
for anything in practice. No application (that I know of) sets them,
and no input method (that I know of) looks at them. How would your new
vertical writing hint be set or used ?
