Why, pray tell, would this be a "fine idea"?

What I really don't understand is what problem any of this is solving,
since in virtually every registry there is a command to check whether
a domain name is available for registration, and it returns plenty
fast.

But adding a third way to find this out, kind of, sometimes, strikes
me as a good way to add to the errors about domain names that people
think are out there, but not really a good way to make anything work
better.

If someone really wants to improve the state of the art with RDS (the
latter-day name for "whois"), there's a whole PDP going on at ICANN
right now about this topic.  It could do with the injection of a
little more technical clue, actually, so I would encourage
participation.

Best regards,

A
