That's actually the contrary of what the specs say today: if M=1 you do
DHCPv6, not SLAAC.

I don't see any statement in 4861 that says that. Per 4861, M=1 means "DHCPv6 is available", not "nodes should do DHCPv6". Relevant text:

      M              1-bit "Managed address configuration" flag.  When

                     set, it indicates that addresses are available via

                     Dynamic Host Configuration Protocol [DHCPv6]

I agree. It’s always just been a hint, no more, no less. And it’s been discussed many times...
