Having the name of the Host displayed in the ENC output can be re-used as Ansible roles example: Red Hat Insights Ansible role has an option "display_name" which we can default to hostname of the host registered which can be either an FQDN (which is by default) or in case a user has set Append domain names to host being set to No then it sets shortname for hosts.

Then Insights remediation scripts would fail to lookup the host from Foreman, which is actual reason for issue reported in https://bugzilla.redhat.com/show_bug.cgi?id=1644832
