I suspect that this will be prohibitively slow in practice. I also suspect this will be very buggy in implementations because DOM implementors will invariably forget to fire all the change records for a change (and a single DOM change can change _lots_ of property values, starting with .innerHTML on every single ancestor, but lots and lots of other things as well). And any time a property is added all codepaths that might change its value would need to be updated to fire change records... -Boris
