It is not unreasonable to require detailed information be kept; it is
standard business practice to maintain such documentation for support,
incident handling, and billing purposes.  If that customer stops
paying  for their service, exactly the right service will be
determined.  It is also required  that exactly the right /32  be
de-allocated;   the previous customer's use of that  /32  can no
longer be used to consider the IP still utilized for justifying future
allocations,  until it is reassigned.

If the provider failed to "unmark" that static /32 as utilized in
their management system,  in that case, it may be ARIN's job to detect
the absence of proof of current utilization for those now-unused /32s.

The provider is required to maintain that detailed level of
documentation, but it is burdensome to publish documentation down to
the /32 level,  hence,  one of the
reasons that it is actually not required to RWHOIS or SWIP, unless
the allocation is a /29 or larger.

That doesn't excuse the provider from maintaining documentation, that
ARIN may require at any time,  it  just  reduces the  operational burden
of constantly updating  external databases with single-IP assignments.

Proof implies that you have provided independently verifiable
information,  that can be
used to show that the applicant is  providing truthful information.

Some "show" commands will show DHCP server usage, but not conclusive
proof of the utilization of the address space.

Because the show commands are not independently verifiable -- for all
the RIR knows,  someone plugged in a big stack of $10  modems  just to
register with the DHCP server.
