all this "tree walking" starts at the root anyway.  And DNS hierarchy doesn't
match organizational hierarchy, so the DNS name (if there is one) of the
validator has no role in this game.
Of course, from an operational perspective, it is wise to make sure the
resolution of your "own" domain names works independently of external
influence.  "Own" of course is a matter of local policy, not to be
fully deduced from the name of the resolver/validator.
