If **[ZONES...]** is omitted, then fallthrough happens for all zones for which the plugin
is authoritative. If specific zones are listed (for example `in-addr.arpa` and `ip6.arpa`), then only
queries for those zones will be subject to fallthrough.
By default, queries for unsupported record types return an authoritative NODATA response when
the queried name has an A or AAAA entry in the hosts data.
* `fallthrough_unsupported` extends `fallthrough` to unsupported query types when the queried name
exists in the hosts data. For example, TXT, HTTPS, and SVCB queries for a name with an A or AAAA
entry are passed to the next plugin. If that plugin is *forward*, these queries are sent upstream.
This option requires `fallthrough` and uses the same zone scope.
