"template.get" returns useless data

https://www.zabbix.com/documentation/3.2/manual/api/reference/template/object lists only 4 template fields :

• templateid
• host
• description
• name

https://www.zabbix.com/documentation/3.2/manual/api/reference/template/get shows "extend" returning a whole bunch of other fields that are useless - disable_until, error, ipmi_authtype and everything else not in the list of the template object documentation
