Yes, that's the purpose.

Yes, this feature definitely targets small-office use, personal use, DB
developers. Don't know enough about data centers to judge the impact
there, but since Avahi - as used in the patch - announces to the local
network only, the impact sould be small.
Still you can tell Avahi to explicitly announce at a certain, non-local
domain, but this feature is not implemented by the patch. Maybe database
developers in large network environments could make use of such
announcements. It would be trivial to add.

The feature is disabled by default. As long as you do not specify a
zeroconf_name in your configuration file, nothing happens. This is the
same behavior as established by the Bonjour code.
