Actually, behavior depends on the parent_domain_matches_subdomains
setting. The default setting includes mynetworks, meaning that
example.com will match host.example.com by default. With mynetworks
removed from from parent_domain_matches_subdomains, .example.com
will match host.example.com.
parent_domain_matches_subdomains is a feature that was meant to
become empty over time.
