This is the key point. And as David well knew when he posted his note,
LIRs are not end sites and are treated _very_ differently. A /32 is
the default minimum size an LIR gets. 

What you are saying here is that there is no "one size fits all policy".

For those not familiar with the
terminology, an LIR is what we usually think of as a ISP or provider,
where the organization provides internet connectivity for a number of
other organizations.

The definition of LIR is different in different Regional Registries. I
can think of at least one region where there is no connection between
being an LIR and providing connectivity to other organizations.

As a data point, ARIN (in the last year) adopted a IPv6 PI for end sites
doing multihoming policy. Such end sites get a /48.

The policy says something different:

"The minimum size of the assignment is /48. Organizations requesting a
 larger assignment must provide documentation justifying the need for
 additional subnets."

(from "6.5.8.2. Initial assignment size":
 http://www.arin.net/policy/nrpm.html#six582)

Again, no "one size fits all" policy.
