That's IPv4-thinking. There are some nice papers on IPv6 adressssing plans and management. One very important aspect is routing. With IPv4 we've got about 600k routes in a full BGP table at the moment. Scale that up by 32 bits and you'll see it's simply not feasable. Another point is the 64 bit interface ID. So it has to be a /64 for each LAN segment. And we'll have multiple LANs in SOHO environments soon (IoT and what have you). For WLAN you should already have a separate network. For a guest WLAN it's another network. So I'd consider 8 /64s the absolute minimum.
