4.5.5 Stateful Address Autoconfiguration Stateful Address Autoconfiguration MAY be supported. DHCP [DHCPv6] is the standard stateful address configuration protocol. See section 5.3 for details on DHCP.
The above MAY should be a SHOULD. There is not mention of stateful support from ND M or O bits being MAY. They simply can be used. It is the option of the user not the standard. To not support any bits suggested for use by users equal to stateless in the ND spec is irresponsible for interoperability requirements in this standards track document. This not being a SHOULD can cause sever interoperability for clients where the user wants all clients to use stateful auto configuration. Any assumption that it will not be used is premature and we should error on the side of it being used. The wording in 5.3 supports the reason for a SHOULD in this section. I could argue it is a MUST but at minimum it is a SHOULD.
