I think you'd want to do a /60 so it's on a "nibble" boundary. But by then you might as well do a /56.

My personal feeling is that 99% of home networks will use a single /64, but we'll be giving out /60s and /56s to placate the 1% who are going to jump up and down and shout at us about it because of some reason that they feel makes it all unfair or that we're "thinking like ipv4 not ipv6" etc.

It's possible that home networks will gain some ability (in a standard fashion) to use more than one /64, but I doubt it - it's much easier to do resource discovery on a single broadcast domain for things like printers, file sharing etc.
