I'm quite unhappy about the trend to put everything in their own  
blocks that happen to be the longest possible prefixes. This means  
that one oversight in prefix length filtering can take out huge  
numbers of important nameservers.

We really need as much diversity as we can get for this kind of stuff.  
There is no one single best practice for any of this.
