No I don't. It seems it is _implemented_ this way, grew organically the
way it is, and now we're defending the 'choice' for these defaults.
I suggest: In absence of an explicit TTL and a $TTL directive, the SOA
Minimum from the policy is used (Zone/SOA/TTL).
If the SOA Minimum is not defined in the policy, then use the zone's SOA
Minumum field value.
Furthermore, make the policy statement (Zone/SOA/TTL) optional.
