Yes. People have been asking for a way to set styles based on the
writing direction, and for the (primary horizontal/vertical) writing
direction to be changeable by the user. The idea is therefore to use
the initial value of 'writing-mode' as a means of communication
between the user and the CSS formatter; the UA would offer some UI
that alters the initial value of 'writing-mode'. So, the initial value
of 'writing-mode' would change from 'lt-tb' to 'depends on user
