I personally didnt have a problem with the first one. But this new version is a better way of accomplishing the goal.
And the "how to advice" can be found elsewhere. It might now be a bad idea to take what you previously wrote and have them put that in NPOG as an example of "how to"
Cheers!

Policy Proposal Name: IPv6 Assignment Guidelines
Author: Leo Bicknell and Ed Lewis
Proposal Version: 3.0
Submission Date: 8/23/2007
Proposal type: new
Policy term: permanent
Policy statement:
Delete the text in 6.5.4.2 and Replace the text in section 6.5.4.1
with the following text:
Assignments by LIRs /48 or smaller will not be reviewed by ARIN.
Assignments greater than /48 will be reviewed to see if the additional
space is warranted according to the 0.94 HD ratio policy. If the
space is not warranted, ARIN will consider the excess space to be
available for a different assignment, lowering the overall utilization
score of the LIR.
Rationale:
The existing section 6.5.4.1 does not provide clear guidance on how
ARIN should treat prefixes allocated to a site should an ISP come
back for additional space in the future. This makes it difficult
for LIR's to know if they are allocating in accordance with the
rules under which they will be judged in the future. The existing
section also provides no guidence on what the LIR or ARIN should
do in the case a larger prefix is necessary.
Timetable for implementation: immediate
