Bare TLD resolutions

Pursuant to

  https://www.icann.org/resources/pages/name-collision-2013-12-06-en)

mentioned in the Scotland thread... it seems there are two major potential
points of possible collision:

1) User network uses "fake" TLD which is no longer fake, and local 
resolver server blows it

2) User network blows it worse, and tries to resolve a monocomponent name
off non-local servers.

The latter would seem to be avoidable by making sure that *DNS resolution
of bare TLDs always returns NXDOMAIN*.

Is that a requirement for a TLD?

If it isn't, does anyone know of any domains dumb enough to actual 
return something for a lookup on the bare TLD?

Is there actually *any* good reason why a lookup on a bare TLD ("com.")
might return a valid record?

And what about Naomi?

Cheers,
