--- Comment #7 from Rafael Weinstein <rafaelw@chromium.org> ---
@Ian, MutationSummary (https://code.google.com/p/mutation-summary/) can provide
you exactly the information you are wanting (and do it efficiently) using the
existing MutationRecord types.

The idea with MutationObservers was to provide sufficient underlying
information so that script can efficiently answer more complex questions.

I'm open to adding more mutation types, but I'm not sure we have a good
justification yet.

Also, FWIW, In Blink, document changes are tracked internally at each node.
Ancestor changes are not.
