This issue actually has very little bearing on the problems with the
Webkit implementation which are much more fundamental than simply
which codepoints are oriented which way by default.  There are a
number of basic problems with the current Webkit implementation, ones
that I've reported [1] and which you, Koji, have commented on.  Not
centering upright Latin is a fairly fundamental problem.

Nor do authors *require* a solution to the question of proper
defaults, since they can always use the values of 'upright' and
'sideways' to manually specify the orientation they prefer.
