I stand corrected, however this is not as big a deal as when sitefinder 
did it because as we've both observed, this is voluntary. If using this 
breaks your application, don't have your application use it, with 
sitefinder you didn't have the choice.

For it's target market: end user DNS resolution, the side effects will 
be minimal if anything.

I don't consider this a different view of the global namespace. If they 
decide to add ORSC root glue or domains then it'll be a 
different view of the global namespace. Hopefully they wouldn't be that

They way we run our applications doesn't lend itself to using it (it's 
that choice thing again), but I've got a few workstations using it and 
one of my laptops. It's also a handy offsite resolver to use to check 
DNS settings from outside our own cloud.

We also get asked our members if there is a viable resolver they can use 
and we'll be happy to recommend this.
