There's a real dollar cost to a registry in performing these checks,  
and a bigger cost in taking action in response to the observed results.

There's a real dollar cost to a registrar in dealing with a registry  
that removes names from the DNS when lame delegations are found,  
regardless of whether they receive notification in advance of the  
removal of the name.

For a commercial registry or registrar, what is the benefit to the  
shareholders of performing such checks and taking corresponding  
action? All I see are costs and competitive disadvantage. "It'll save  
ISC money" doesn't sound like a winning argument :-)

Personally, I wish there were no lame delegations anywhere in the  
namespace, but I struggle to see a business case here. If there's no  
commercial motivation for doing it, why would anybody expect it ever  
to happen without regulation?
