I never could understand the motivation behind RFC3531. Just assign /64s. A single /64 subnet has 18,446,744,073,709,551,616 host addresses. It is enough. Period.
With IPv6 when you think of assignment to end-user, it's better to think in terms of 'use case' rather than number of hosts within a single network. As a residential user I might have wifi, voip, TV, CCTV,,... each of them can use its own prefix. As a bare metal user in a datacenter , I might have different needs when I build any internal networks. As a corporate user, I think this one is the more obvious. The only end-user who might stick with a single /64 is - 1 smartphone - 1 VM -- Willy Manga
