This actually would be a good thing in this case. The responses we got weren't quite positive (which is actually quite a positive description of the responses we got) but I don't see that the GACh RFC is actually disallowing it. Still we would need to go back and make changes to a few RFCs. That was also something people weren't really happy about. Again, these were some of the constraints we worked with which led to what is on the table right now. We weren't blind to HW considerations, vice versa as you can see when you look at the appendix that was removed in the latest version of the document.
