This is precisely the problem my admittedly kludgey suggestion is  
supposed to solve. If the registry (zone operator) has a policy to map  
as desired, then the upgrade works as hoped anyway. We could even  
include a mechanism to say "never had any idna2003" so that people who  
have waited for something better get the new benefits as soon as new  
browsers are deployed. (But the idea is still a pig, & I'm not  
defending it hard.)
