It is. Any object (including proxies) is a still a truthy value. 
Something like value proxies [1] (not in the table for ES6) would 
probably be more appropriate to make document.all self-hostable.

I'm not 100% aware of all Window/WindowProxy intricacies, but from what 
I know, Window/WindowProxies can be expressed as objects and ES6 proxies.
If you don't think that's the case, please describe cases where you know 
(or have a doubt) it isn't so we can discuss that.
One goal for proxies is being able to express Web APIs in JavaScript 
(with the notable exception of document.all), so it's important to know 
if that's not the case.
