For what it's worth, that doesn't appear to be necessary for web

The HTML spec requires that property access on documents use effective
script origin for checks.
Effective script origins are mutable.
It is in fact possible to get your hands on a document in a different
effective script origin in WebKit (thanks, document.domain).
Just saying,
