I think the following things need to be decided:
1) What should the behavior be for WebIDL objects going forward?
2) If the going forward behavior is to have properties non-enumerable,
should we try to migrate some subset of the existing Web IDL
objects to the new behavior?
I'm pretty sure we can't migrate all existing things, at least without
breaking someone somewhere, but I suspect we can migrate many of them,
if we decide it's actually worthwhile.
I'd be pretty interested in knowing what other implemntors think here,
because if we make some decision on #1 I'd rather not have people
continue to ship whatever they do now instead of what we decided on.
We've been having a _lot_ of that happen with Web IDL. :(
