yes, i know, and i'm strangely OK with that. market chaos will be 
painful, and could drive dnssec adoption, if the only standard way to 
get some cool new thing is if you have an NSEC bitmap to work with.

we should have cut off EDNS-incompatible name service clients and 
servers who could not either implement, or signal nonimplementation 
successfully, after 2004. five years should be enough, but only ever 
will be enough if there's Tough Love somewhere in the equation.

right, which will hurt their addressable market calculations. bring it on!
