The answer is inconsistent. Some DHCPv6 clients default to a /64 prefix so that this scenario works, and systems with those clients can and do interoperate. The obvious complete solution to this problem is to deliver the prefix length via DHCPv6, at which point you may as well also deliver a default gateway, and complete the circle that starts the deprecation of RA. Link locals are not sufficient as they are unlikely to appear in DNS.
