I think it's unlikely that the rotation hack's results would be "flawless"
on any but the simplest texts.  Among other things, vertical Japanese
requires special line-breaking rules - such as period and comma protruding
into the bottom margin if they would otherwise appear at the start of the
next line.  Vertical Japanese is usually set on a grid, both horizontally
and vertically, and grids have always been a problem for TeX - it likes to
make spaces stretchable and expand lines to accomodate math, all of which
features have to be carefully tweaked to preserve a grid layout.  Western
text mixed in raises its own problems; depending on context it might need
to be rotated or not, and the spacing rules for it are unlikely to match
those of generic (La)TeX applied to rotated glyphs.
