according to the documentation, you need at least a host service pair
(which can be overruled by the hostgroup directive). but only defining a
dependen hostgroup is not enough - you are still required to add a
dependent service to your definition. And that is what the config
verification is trying to tell you.

yes.

this is due to the nature of how config is being read, parsed, and
processed later on improving might require a full rewrite though.
