Yes you can hijack something that doesn't exist (for varying values 
of existence).

This is the same situation that the RIRs faced with the bogon lists 
for IP address prefixes.  (The problem peaked as recently as 2005 - 
i.e., it was a recent one.)  ISPs would filter out all traffic to the 
unallocated slash-8's (as listed by IANA as inactive).  When an RIR 
was allocated a slash-8, even an announcement on mailing lists wasn't 
enough to get all filters changed.  Now the RIR's put in test 
addresses for traceroutes and pings to allow checks for bad filters.

If the browsers do implement a check based on TLD name, I bet they 
are also gullible enough to implement RFC 3514.

Keep in mind that there is more than just the ICANN root zone DNS in 
the world.  Perhaps the thought is that it is the only legitimate 
root zone on the global public Internet but there are other global 
inter-networks.  These networks also employ DNS albeit operating 
under a private administration.  A browser that is hard-wired for the 
global public Internet would be a problem on these private networks.
