My take. When a node reboots, the first thing it *always* does is
solicit an RA. When it gets the response RA, it has new information
that overrides the old information. So the old information isn't
relevant. That information either says invoke DHC or don't.

If it *doesn't* get an RA, that implies there are no routers. But the
ND (or addrconf?) spec already says that if there are no routers, then
you invoke stateful.

So I think no special words are needed, reasonable behavior is already
defined elsewhere.
