One reason is that this supports setups of the following type:
- ns01 is a powerdns machine in slave mode, slaving domains from other machines.
- ns01 stores all slaved zones in a database (MySQL, Oracle, etc.) which is 
replicated to one or more database slaves
- ns02/ns03 use these database slaves in readonly mode.

In this case, all three name servers see 'type=SLAVE' on many domains in the 
domains table, but only one of them should actually be slaving.

Kind regards,
