Your proposal solves *one* problem (the one well explained by Andrew
Sullivan), the difficulty of having an up-to-date list in the
installed browsers.
 
It leaves open the other problems:

* Difficulty of managing this list (and even worse if every browser
  vendor ask the TLD managers for a slightly different info)
* Administrative boundaries at lower levels (if we delegate under
  ".fr", it says nothing about x.example.fr and y.example.fr: are they
  in the same administrative domain?)
* Mozilla's methods of arm-twisting
