A big problem is that "consensus" for WG21 is actually just "Did the chair of your sub-sub-committee say there was consensus?" and is typically measured by voting. That's not a consensus, it's a majority. If you've worked on technical problems with an IETF Working Group you'll know what actual consensus looks like. If you've been around a while you might even have seen abuse of process used to dodge rules and seen demonstrated before you why we need consensus anyway. ISO's procedures are probably adequate for its original goals but they're completely inappropriate for designing a programming language. SC22 should never have existed and is entirely the wrong place to do this work.
