Indeed. Perhaps this can be clarified if 2671bis gets revived. After  
all there is a difference between "I don't speak EDNS0" and "I don't  
understand this EDNS option". Until then, it would be prudent for  
anyone proposing new EDNS options to specify how implementatons that  
don't support the option should behave. Your mileage may vary.
