Pasta, the ToC being annulled as a result of a provision in the ToC goes against the spirit of its annulment, doesn't it? I say that, since it is the non-signatories forced to obey the ToC who suffered the most as a result of it, it should be they who decide whether it is to be discarded or not. Being that none of those powers support the ToC, it's discarded by default.
