The policy was implemented September 2010.    That is approximately
1.5 years ago.
The fact hundreds of applicants occured showed success of the policy,
not a failure or err'ing of the policy.

If the renumbering requirement were considered too burdensome, no
organizations would have applied for a /24  multi-homing assignment.

 Did  ARIN go back  to  the  organizations that received a  /24 under
2010-2  more than 12 months ago,  but did not make additional
allocation requests,   and survey them    to determine if they
obtained additional IP addresses from another source  following their
/24 allocation?

There is an alternative explanation:  perhaps they did not need more
IP addresses,
or   they didn't need them very much.

If they availed themselves of the new rule and carefully planned for
the implications, its quite possible they had plans  that would avoid
the need to renumber within the foreseeable future or make it worth it
by the time they needed to.

There really is  no indication the policy has err'd in this case --
it seems to have been successful,    there is limited routing table

It is not clear what kind of impact removing the renumbering
requirement would have on number of applications;   I would anticipate
the number of  /24  small ISP multihoming applications could increase
massively,    due to a large number of organizations seeing  removal
of the renumber requirement as a  reason  to go to ARIN for PI instead
of upstreams.
