What about if (say) ISC, NLNetlabs, Nominum, PowerDNS and Google DNS say
"enough is enough"?  

Because right now, the dynamics we all know are "yeah but you must fix it
since it works on X" (where X isn't you).

If we had a nice manifesto to point to, we could make this stick.

I estimate that >25% of the PowerDNS recursor now consists of "stuff we have
to do because the internet sucks". 

The horrible thing is that every workaround we add increases the chance we
break legitimate things, or open ourselves up to attacks that make good use
of our willingness to bend things to make them work.

Benno, Wilmer, Ted, Kumar, what do you think? We could coordinate off-list
perhaps?
