Interesting. I think this swings towards the idea I put forth earlier on
the list ("Auto-fonts", 10 May 2004). I concentrated a bit more on the
ATSUI (Apple) side of the implementation, and that it concerns font

At the time, I said, and Jonathan replied:

I think people are arriving at the idea of these fallbacks are more than
typographic chance, more design. And that it's useful to set these things
up as templates or formats for automated/on demand use.
