So, this is more of a 'opinion' / 'feel' (with all due respect) comment, and not something which has a (presently) compelling technical reasoning behind it ?
Think of something like HIPnet https://tools.ietf.org/html/draft-grundemann-homenet-hipnet-00 http://www.cablelabs.com/the-future-of-home-networking-putting-the-hip-in-hi... with multiple levels of home devices performing routing (prefix delegation), with multiple networks off of each. Even a /56 can easily end up being too little for multiple levels in a residence. If one believes in the IoT/IoE hype, everything will have a IPv6 address, and many of those devices might have multiple internal networks. So, yes, I assert based on a "feel" that a /48 is the right choice, because I am hoping to not make the same mistakes as with IPv4, and under estimate the growth of the network by the customers, resulting in all sorts of convoluted workarounds for not having enough addresses and options to do things right.
