Concern shared.
Yes, that's required.
Would it make sense to leave ECMAScript spec intact (global's
[[Prototype]] is implementation-dependent), but have WebIDL put
requirements on the prototype chain?
That would allow non-web contexts to have null as [[Prototype]]; and
some people seem to want to do that [1].
I imagine that code that requires the global object to inherit from
Object.prototype is code doing "window.hasOwnProperty('whatever')" which
is only needed for web compat and isn't really given modern JavaScript
practices.
