Having a DHCP server generate RA messages kind of defeats the point of
having RA messages
in the first place,  resulting in loss of robustness, and now a new
mode of failure.

The point of having RA messages is they are simple,  and integrated
into the routers,
so there is not a separate server to fail  (a "DHCP server")  to cause
loss of connectivity,
due to  server appliances (computers)  being less reliable than routers.

With the RA integrated into the routers properly,  clients can
maintain connectivity
(and establish connectivity, provided DNS details obtained in the past),  even
if  DHCP server(s) should fail.
