Why? What problem are you solving by changing the current behavior?
DHCP must support defaultroute and must be decoupled from RAs, no M-bit or whatever.
M-bit is a hint, nothing in the standard says a host isn't allowed to use DHCP on a network.
(tons of options on how DHCP and RAs can live together, all with their own pitfalls. From the simple one that dhcpclient can disable the kernel from accepting RAs with it's own pitfalls, to let the kernel sorting them out, and over to preferring either one - RAs or DHCPs defaultroute)
Personally I think it's a huge mistake for an implementor to have the kernel process RAs, all this control plane should be done in userspace, not in the kernel.
