Yup, I got init, medi, fina, liga, rlig, mark and mkmk to work, at least
those are the ones I tested. I used some thing like:

\font\arab=name:myfont:mode=node;script=arab;language=ara;+init;+medi;+fina;+liga;+rlig;+mark;+mkmk

Very verbose :) but it does work, and we can make sets of defaults so
that setting language and script is enough to get default features, as in
XeTeX but even better, in XeTeX you can't disable default features.

I see.

That is my point, we already have code that is working now.
