As of today, the current LTS release is 4.0. So I took the chance to compare the current jinja Template against the default file for Debian 9 stretch from: "http://repo.zabbix.com/zabbix/4.0/debian/pool/main/z/zabbix/zabbix-proxy-sqlite3_4.0.3-1%2Bstretch_amd64.deb"
IMHO all the default comments should be completely added to the config file, to make it more understandable. And if I see it correctly, this is already the case for the Zabbix Agent jinja Template.
I also added missing values for 4.0 with IF querys.
I also added missing default values for Debian to the map.jinja.
