That's possible, but there are many conflicts with this.

It has a few downsides:
1) can not resolve local names like .home.arpa

2) can not resolve anything if there is no Internet, which makes it hard to
   login to CPE device to find out why there is no Internet.
   
We've had this conversation multiple times, so I'm not quite sure why this is
a surprise.
