That should probably be a reference [DHCPv6lite], or you should say
DHC Lite instead of DHC?

Yes, the change log for 2462bis says
o Removed the text regarding the M and O flags, considering the
maturity of implementations and operational experiences.
ManagedFlag and OtherConfigFlag were removed accordingly. (Note
that this change does not mean the use of these flags is
deprecated.)
Which explains why it was removed.
Note another changeklog in 2462bis talks about removing references to
stateful configuration:
o Avoided the wording of "stateful configuration", which is known to
be quite confusing, and simply used "DHCPv6" wherever appropriate.
Maybe the text above should reflect that, and just refer to the DHC
variants without explictly mentioning the s-word?
