As far as I can tell the coding guidelines are silent on this particular
issue:

http://bind10.isc.org/wiki/CodingGuidelines

We happen to have one example of enumerations in the "Naming" section,
which looks like this:

enum EnumName {
  THING_ONE = 1,
  THING_TWO = 2
} enum_instance;

So maybe that was interpreted to mean that we always use manually
assigned values.

Like Jinmei, I also have no strong preference, but I tend to lean
towards preferring allowing the default values. If we need manually
assigned values we should use them, but otherwise not.
