Isn’t that something Fantasai proposed in 2005 (albeit referencing a now outdated CSS draft)? <http://unicode.org/notes/tn22/RobustVerticalLayout.pdf?page=25>

Instead of glyph transformation (‘translate’ or ‘rotate’), one could specify glyph directionality, an inherent property, as 
– either  ‘planar’ / ‘absolute’ (like north, east, south, west),
  i.e. the opposite of block progression (which is the progression of lines),
– or ‘linear’ / ‘relative’ (like top/up, right[wards], bottom/down, left[wards]),
  i.e. orthogonal to inline progression (which is the progression of glyphs).
