This is the equivalent of a negative research result that looked into whether there's anything more to explore here to produce the really juicy result like a true compromise, but instead shows that there's nothing that a set of highly qualified researchers can prove, at least. I applaud more of this, although it is not an infrequent practice among the top security engineers, I feel it sets a precedent for research broadly.

Nothing to be found here as far as we know, is still a result that deserves publishing. Let's make it more of the norm.
