Just my humble little opinion, but we have lived with the rules as written for lo these many years, and trying to push through this rule change as a clarification is leaving too many holes in the scenarios.
Even if the rule change was not passed due to a snafu at the national convention, what's the harm in living with the rule as written for one more year?
Fix it next year with a well thought out, well written rule.
Well, at least reasonably thought through. Well written? That might be asking too much!
