What purpose does it serve?

As an example, if i delete an entry, the fact i deleted an entry is 
of interest to some manager in user space for the purpose of syncing.
If i brought a link down, same thing. If i brought a link down
that was already down - why would that be of interest to generate
as an event? etc.

cheers,
jamal
