Section 4.2 says:
Note: If neither M nor O flags are set, this indicates that no information is available via DHCPv6.
It should say:
Note: If neither M nor O flags are set, this indicates that no information is available via DHCPv6 from the router, or from other nodes that the router has been made aware of.
Notes:
M=0 does not prevent a node from attempting DHCPv6.
The router cannot definitively know that no other DHCPv6 servers exist.
RFC 8415 does not require M=1, with §18 providing other examples that may trigger a DHCP exchange.
