We (this working group) had that discussion in 2007 when policy proposal 2007-08 was introduced. At the time it was decided that reallocation (transfers) were a better / more viable solution than trying to reclaim unused addresses. Please take a look at the mailing list archives to see how the discussion went. It was a quite long discussion.
