2) element transformation. The replacement fires "after" a mutation. Library or tools that want to transform the application dynamically want to get notification "before" the mutation.

This really only works if you trust the listeners. The browser core can't trust scripted listeners using Web APIs.....
So, for example, I can't see how to implement JS pre-processing using only the after event. (This may not be possible with the current mutation events either, but it is something I want to to).
It's not clear that you need a web-facing API for your use case, though.... -Bori
