  // deregister regular services if they happen to be registered using the same
  // ID scheme as our sidecars do by default. We could use meta but that gets
  // unpleasant because we can't use the consul- prefix from an agent (reserved
  // for use internally but in practice that means within the state store or in
  // responses only), and it leaks the detail publicly which people might rely
  // on which is a bit unpleasant for something that is meant to be config-file
  // syntax sugar. Note this is not translated to ServiceNode and friends and
  // may not be set on a NodeService that isn't the one the agent registered and
  // keeps in it's local state. We never want this rendered in JSON as it's
