IE's support of vertical text is based on using the 'writing-mode' property as defined by CSS-3 and XSL-FO for a number of years now. There are implementations of 'writing-mode' other than Microsoft's IE that support the 'writing-mode' property. 
I still don't see a need to change something that is already working. CSS has markup specified that handles most samples in Elika's document. Adding the 'reference-orientation' from XSL-FO would allow for all examples in the paper to be rendered in CSS. 
Keeping CSS and XSL-FO in syn and keeping existing web pages working as they were designed is of great importance.

The existence of deployed content would make it more than simple
implementation, but how would dependence on existing functionality
negate the viability of a different specification which provides the
same functionality?

As I understand it, Internet Explorer's implementation of vertical text
is based on Microsoft extensions to CSS.  Even if CSS adopts a different
specification, support for these extensions could continue in a way
which is transparent to the user.
