  clients do.) This will break some downstream unit tests that were testing
  `result == nil` rather than `err != nil`, and in some cases may expose bugs

### SIG Network

For 1.13, the areas of focus were in IPv6, DNS improvements and some smaller items:
CoreDNS is now the default cluster DNS passing all of the scale/resource usage tests

Previously, there was no formalization of property naming; only loose conventions were followed.
While these conventions served relatively well in practice, they created gaps, resulting in a loss of uniformity in some cases and leaving friction in the process of naming new properties.
