If we did this, I suspect what would happen for the foreseeable future is
that all reclaimed space would be assigned out as /24s to everyone willing
to accept a /24 to fulfil their request. Anyone who insisted on a larger
block would get nothing, so there'd be no incentive to do so. That would
have the effect of giving a small number of space to the largest number of
organizations possible, which could be considered a feature or a bug
(increasing the number of routes that have to go into the global BGP table).
