{speaking as a WG member}

synonymous, I think that we are not insisting that each method have identical
names, because there might be different connectivity to each. Imagine:
       "ipv6.portal.example"
       "portal.example"
       "v4.portal.example"

and since DHCPv4/v6 can customize the answer with a URL that includes
a ?query, while RA's can not, that it a further reason why they might not be
the same.

The sentence leading up to this word speaks of different classes of clients already.

HOWEVER, I think that we might be in error in section 3, where we say that
they have to be identical. Oops.
