PKI User Authentication Into the Frontend

Since we've started using Zabbix, we've modified the PHP to enable PKI authentication into the Frontend. A user account is still required to be created by someone in order to be authenticated (we prefer this so that users can be added to usergroups that they need to see alarms for and not everything), but our organization is fully PKI enabled and its just easier to present a link in index.php to sign is as <user> where <user> (in our case) is the value of $_SERVER['SSL_CLIENT_S_DN_CN']. Plus, it meets my organization's security objectives.

Are there any plans in the development team to implement this natively in the future? If not, would you welcome a merge request?
