Which is irrelevent to removing a address block on the basis of a
RIR recording that the block has been reallocated.  A reallocation
already goes through a quarantine period though that may get shorter
as time goes on.

A transfer on the other hand doesn't.

There may be some use in recording whether a address block is
transfered or allocated.  Note I'm not sure if the allocation
date gets updated on a transfer or not.

There may be some use in recording when a address block is 
quarantined.
