Don't get me wrong, I wasn't trying to dismiss the thought, but was
playing a little devil's advocate myself. Back in May I offered up some
thoughts along a similar line. 

What you say is true, provided the "best fit" allocation made to
organization X provides an adequate window of time for other
organizations to get to the remaining reserves. This would leave little
or nothing left by the time org X comes back, as you mention. 

The problem comes in when you have an org that can justify a /12, and is
only given a /17. This scenario is where you would need a time
requirement restricting future allocations for some number of months.
Without a time restriction, there is nothing to prevent that org from
submitting applications every other day and depleting what's left before
anyone else can get to it.

I don't know if this potential proposal is a good idea or not, but isn't
the point of it that by the time the org uses half of their
qualification (three months later), ARIN would be completely out?

Org qualifies for /15 but gets /17.  During that three months, the other
/17, /18, and many of the /19s are assigned to others.
Org qualifies for a /15 or /16 but gets a /19.  Maybe a month later they
can get a /22, but by that point IPv4 is gone.  The goal (I think) would
be to distribute the last assignments among more organizations, so that
one well-timed mammoth application does deplete the remaining pool,
meaning Mammoth ISP is the only one who growsv4 that year/ever again.
Mostly playing devil's advocate.
