That's true, although doing such things at the macro level carries a
risk of undesired interactions with other packages.
I wonder if a similar approach to hanging punctuation could be
implemented using \XeTeXinterchartoks, though; that might be less
intrusive as it doesn't involve making the characters active.

Well, it wouldn't require a "re-write of xetex", it's an extension
that could be implemented within the existing program. I'm open to
considering a patch, if anyone out there cares to do it. :) (If I
didn't have to spend time earning a living, I'd have tackled it by now!)
