This CAN BE necessary, depending. This option has a valid use case with SLAAC+DHCPV6 (stateful or stateless) for DNSMASQ router advertisements. The default RA DNS FIELD uses the link-address fe80::/64 and many hosts will use that as primary. However, fe80::/64 is ideally only for link functions, addresses do not resolve as host names, and it can make logs/diagnostics look weird. So the option above will instruct DNSMASQ to RA the DNS FIELD of its interface with respect to global-address or unique-local-address fd00::/8 the RA is for.
