Yeah, the point is that you can interpret what's in 1034 too many 
different ways to say one has to be or the other.  Strident claims 
can be said that "glue is glue" and that would seem to be wise, but 
people actually running the name servers out there had reasons to go 
with glue as if it was cache.

My preference, given the choice between an running system and a 
compliant system, is to go with the one that runs.  The world wasn't 
built to conform to a specification.

 From what I've been learning, it's more than one resolver.  What 
happened in history is that one implementation got it wrong, a second 
implementation was then coerced into bug-for-bug compatibility, and 
then another and so on, so that the bug was repli-engineered into 
many places.  Eventually, the bug became the law of the land.

It's not the first time nor the last this has happened.
