As the author of the policy which set this block aside, I speak only from my=
 perspective as the author and not officially on behalf of ARIN or the AC in=
 any way:

The intent is to provide very small allocations/assignments for organization=
s which need some amount of IPv4 for a best-effort to facilitate networking a=
fter IPv4 general runout.

While I recognize that organizations may or may not be able to get these rou=
tes accepted, the reality is that IPv4 runout is going to create interesting=
 routing scenarios and other problems. I figured having a predictable prefix=
 where people could at least make a best effort was better than simply allow=
ing chaos through the entire address space.

Indeed, much popcorn will be required. That is why my networks are all IPv6 c=
apable already.
