That is entirely a matter of opinion, and one frequently debated still.

FWLIW - I think RAs are a perfectly fine way to distribute information about
the router itself, and to provide hints about the environment (e.g. - "Yes,
we do Stateful DHCPv6 here ("+M", and "+O' as well" ...)

Disagree - rogue offers affect people without a lease, so the impact  
of an attack is not immediate.  Filtering DHCP on v4 is well  
understood, an update to current operational practice rather than a  
new system.
