I fully agree. I think Anne has a point, and a change to the CSS3
@font-face spec as Vlad outlines here will answer that point.

I think for WOFF to achieve its aims, this WG needs to agree on
specifying that SOR is the default behaviour for at least WOFF, and
better, all fonts.

(Also: I apologise for not participating more fully in the WG the last
few months, I've been busy with work :-)
