Stateless DHCP options "authorized" in RAs, in a standard-format container

No.
Again, no one is obliged to implement it in any device.
But those who do it (to increase efficiency), have a standard format to do it.
Deployment is incremental and can remain partial.

The point is that authorizing some DHCP options in RAs is more powerful, and simpler, than RFC 5006.
This way should therefore, IMHO, be preferred.
