It wouldn't do anything really special, except making the RR in
question (probably a SOA) talk about the DNS root instead of whatever
zone you are into. Which will probably cause an out-of-zone data
error.

Lots of people do this with internal root setups. You just have to
make sure you get it right, *especially* if you want to be able to
resolve Internet domain names.

That is when it starts getting tricky.
