have you actually built large-scale UI applications using a
one-size-fits-all observer model, or are you just guessing?

in real life, "something happened" is almost entirely useless,
and the other extreme "this and this and this and this and
this happened" isn't much better.  to get performance, you
need to think in data model terms...
