You're right on the money with that one - timber frame + SIP IS a bad idea. I have always thought that, since I first got interested in timber framing in the 90's. I did a recent blog posting (yesterday) at some length on that topic in fact. There are excellent alternative solutions I believe, though 'perfection', as such, is unattainable. Let's say there are better adaptations and wiser uses of material, methods employing local materials and lower embedded energy building. I'm planning to spend a fair bit of time exploring that topic in coming postings on my blog, so I'll hold off on commenting further here.
