I can't speak to APNIC's procedures.  With respect to ARIN, your summary 
refers to the future, and I have only stated that our historic practice 
has been to redistribute </8 sized blocks and to return /8 blocks to IANA.  
I do not know about future practice; that is subject to the policies which
are developed in the ARIN region and guidance from the ARIN Board. 

With respect to ARIN's historic practices in this area, I note that when 
InterNIC registry services were transferred from NSI to ARIN, we continued 
to use existing practices, and since space was being allocated to RIRs at 
the /8 boundary, return of address blocks smaller than /8 to IANA did not 
actually make space available for reuse for another RIR.
