Re: [heycam/webidl] Are operations on the `[[BackingMap]]` and `[[BackingSet]]` page-hookable? And if not, why not? (#254)

It's not quite unobservable, because of the iterator question.

Not having a backing map/set at all requires reimplementing and respecifying a bunch of iterator infrastructure...
