Bacteria do not make secondary modifications, and yeasts usually over-glycosilate proteins. That's one of the reasons, why large proteins for instance antibodies are produced in mammalian cell lines.

Yet I agree, a rice or corn based expression system would be much more efficient, but to approve those 10+ years would be needed. And it seems that Kraig Biocraft has some kind of umbrella approval for GM-silk moths in Vietnam. As inefficient as this may seem, from a regulatory standpoint it is a gold mine, the only possible molecular pharming platform on Earth that has been approved.
