That's an unsound assumption. Think stub resolver search configurations. A resolver might be depending on a lookup returning NXDOMAIN/NOHOST so a next name in the search list is tried to eventually bring the user to their favourite website with pictures of kittens or whatever. Pointing them at an address in 127/8 or some (presumably ICANN run) thing which says "you've come here because of a gTLD collision" is not going to have a happy ending.
