at least two problems with this approach:

- delegation does not imply announcement or reachability
  DNS registration should -NOT- do the same, but it does.
- People thus far have not been willing to deploy the segmentation
  needed to split DNS delegations along CIDR bounds.  Until then
  we are "stuck" with classful alignments in DNS.
- This was considered and abandoned as another attempt to overload
  the DNS.

The flaw in this approach is that the top level delegation point 
can always override any downstream delegation point. (can you say
restraint of trade?  Sure you can..)

Still this approach has been looked at and it has a couple of really
nice technical points.  It will be stronger when we get SIG RR's 
and dynamic update.  Perhaps we can revive it?
