A simpler solution that is free from the faults listed in that email 
would be to have (at max) one mutation observer for the whole page 
context. I guess this would be called at the end of the task or 
immediately before page reflows.

If a js lib (or multiple libs) want to provide finer grained mutation 
handling then let them work out the details.
