Why would the correct answer not be from foo.bar.example.com or
bar.example.com (or, actually, both)?

A large amount of the assumed background is the deployed convention of
label.example.com.  The "registered domain" here is example.com.  And
while that is the most common case, it doesnt cover everything.
Indeed, if that convention _were_ reliable, we wouldn't need the
public suffix list at all.  

Moreover, if my parent can assert things about me, then unless I run a
WEIRDS server I wouldn't have a way of disagreeing with that parent.
