*-visible vs *-announced (what's the point?)

I've been thinking about this and the distinction makes almost
no sense to me.
The same information is being made available (is xxx on the system) except
that with *-visible exposure, the viewer needs to request the information.
I see this as an optimization, not as information control.
To illustrate the point: I am considering writing a znol-type program
which would do a ZGetLocations() every 30 seconds or so. This would be a
globally bad thing because it would load down the servers (especially
after I gave it out to my friends).
In summary, I believe that if you are *-visible, the servers should provide
notifications upon request to interested parties, as an optimization w/r/t
server load and pinging znol-type programs.
