Progress continues on Valhalla, and this is clearly where things are 
going, but integration is not imminent.

But, the main point here is: if the goal is to protect broken programs 
that make incorrect identity assumptions, said protection is inherently 
short-term; when Valhalla lands, all these programs will be broken, and 
there will be no interest in punishing the other 99.999% of code just to 
continue to coddle them.  So we should be clear that this is at most a 
short-term reprieve.
