This is really a no-brainer. The requirement to SWIP or rwhois
assignments down to /29 is a separate issue from the requirement to
demonstrate efficient use of IP space. Also note the "including but not
limited to" phrase below, which implies ARIN could ask you to document the
usage of every single /32 if they felt it necessary.
ISPs are required to demonstrate efficient use of IP address space
allocations by providing appropriate documentation, including but not
limited to assignment histories, showing their efficient use.
220.127.116.11.1. Reassignment Information
Each IPv4 assignment containing a /29 or more addresses shall be
registered in the WHOIS directory via SWIP or a distributed service which
meets the standards set forth in section 3.2.
If you could "hide" behind "these blocks are all /30 customer
assignments, that's all you need to know", then a member could just lie to
ARIN and say all (or >80% of) their space is in use, and request more Of
course, you could also just make up a bunch of customers too...but that
requires a bit more creativity than "you don't need to see the customer
info for these /30s."
