As Pekka pointed out, in draft-iesg-ipv6-addressing-recommendations-03.txt
it states:
"In particular, we recommend:
- Home network subscribers, connecting through on-demand or
always-on connections should receive a /48."
OK, so it is a recommendation, and ISP's can, if they choose, offer a
static (or dynamic) /64, at whatever price they choose.
(One comment for the IESG here is that in only one example is static
allocation specifically mentioned; perhaps this should be considered
for the document as a whole?)

I think the market forces will lead to static /64's being available
free of charge. There will be enough providers who can offer that for
free, that those charging extra will lose business.
While the recommendation may be a /48 (which may of course be subject to
a charge by some providers) it's questionable at present as to whether
any home networks would use it in the early deployment.

You assume that the /29 can be deployed in such a way that there is
100% utilisation. Is that really the case? (If I consider how a /29
may be used by a national academic research network provider, then
the regionalisation of the networks mean it won't be, and on top of
that you would presumably be making an address plan with growth in
mind, e.g. for regional PoPs).
