IMHO, we should expose a more targeted API for your use case.  Exposing mutation observers to Chromium creates too much of an incentive for developers to implement poorly factored designs that re-implement web platform functionality in the embedder.

I have a hard time believing that we cannot create a more narrowly scoped API for your use case.  If we were to implement this feature internally in WebCore, we certainly wouldn't use mutation observers to react to changes in the page.  Many features in WebCore already need to react to changes in the page, and we implement them more specialized mechanisms that don't impose performance penalties.
