I would think it would be an obvious win to work together with pango upstream for doing pango/cairo integration as efficiently as possible.

I think that that's all that Behdad meant when saying he "can't and won't spend time making it faster". If mozilla does its own custom integration of pango with cairo, then mozilla owns it, and there's obviously little that pango maintainers can do about that.
