In reviewing IPv6 end user allocation policies, I can find little

slightly preferred.

I am most curious as to why a /60 prefix is not considered when trying
to address this problem.  It provides 16 /64 subnetworks, which seems
like an adequate amount for an end user.

Does anyone have opinions on the BCP for end user addressing in IPv6?

For business customers I would give /48 and home users who might have 1-2 subnet I would give /56 or /60.
- Business customers night grow where you have to provide bigger amount of subnet - allow space for future extension -

- Home users - they usually don't know what is subnet. Setting up different subnets in their SOHO router can be 
difficult. Usually the simple 1 subnet for every device is enough for them. Separating some devices into  a separate 
subnets is usually enough for the most sophisticated home users. If  not then he can opt for business serviceā€¦.

This utterly ignores the reality of DHCPv6, DHCP-PD, and technologies currently being developed for rational automatic 
hierarchies of topology.
