I guess from my point of view, extending the existing member 
[Unforgeable] to a wider class of members without changing anything else 
about it seems simpler than having two separate meanings to 
[Unforgeable] depending on what it's decorating...  But maybe we're 
thinking about simplicity in different contexts?

(Note we'll still need single-readonly-attribute [Unforgeable] for 
several properties on Window and Document, no matter what we do with 
Location.)
