Rick,
It's true that allowing user-invented custom attributes will not break any
important existing invariants (except perhaps that all existing descriptors
can be assumed not to have any own properties besides the standard
attributes. Existing code may depend on that, although it feels highly

ES5 code expectations aren't met:
The only case where ES6 and ES5 may diverge is for
Object.getOwnPropertyDescriptor
where a Proxy may return something that
By the same token, it is feasible to postpone these custom attributes till
ES7. My concern is that since the [[Origin]]-oriented proxy proposal that
has been in the draft spec was a distracting dead end[1], we should be
conservative in returning to the design that preserves the crucial
