I agree, FWIW -- I was focused on [[Prototype]] due to the __proto__  

Still, if the intention of the proposed spec language change is to  
make sure implementations treat o.__proto__ as not writable when  
Object.freeze(o), e.g., is called, then calling out [[Prototype]]  
would increase the odds of achieving the intended goal.

Mentioning __proto__ would increase those odds even more, but it is  
hard to name that horror without inducing madness (shades of  
Lovecraft ;-)).
