as a provider, where is the win in this for me? the space is 'lost', i.e. committed, and i increase provisioning hassles, though maybe mildly if i am skillful. if/when the rirs sober up about ipv6 justification, i will have a hard time showing an hd ratio without a lot of zeros to the immediate right of the decimal point.

or would you suggest that i recover the committed space if unused? under what conditions? after how long? and, when i recover, do i allocate the second (or 42nd) /64 to a new customer, leaving them a smaller cushion than the first user of that /56 received?

no easy answers. but yes, giving them a /56 off the bat feels a bit reminiscent of giving them a /24 in ipv4.
