Yes after writing that I thought that it was already based on on:send: so you only broadcast to the person that register.
Another question , which Stephane noted already, is the overhead of broadcasting.
First of all, announcements are magnitudes faster than the ancient change-update and trigger frameworks.
In VW I would have problem to see why this was that slow especially since they clean the update:/changed: to have exactly on:send:....
The problem of broadcasting does not apply to announcements, because the observer only registers and receives events he is interested in.
