This particular generality worries me. As I understand it, conditions become a registry matter, not an RFC matter. I fear the proliferation of conditions that nobody will implement, or worse similar conditions with slightly different semantics that somebody prefers to existing registered conditions.
That doesn't strike me as a problem. We have lots of protocols with registries full of little used or unused optional extensions. SMTP is a good example, and it interoperates pretty well.
