That seems painful when fast action is required.  Say 
you have a /16 and someone is hijacking a /23 withing it.  
Before mitigating damage by announcing the two /24s 
you'd have to update the registry and wait for the 
upstream to accept it?  Do you just preregister all the 
/24, /23, /22, etc prefix combinations in advance?
