IF we assume and prepare the ground for aggregation, would that just make 
it easier in the future for this type of addresses being leaked?

Anyway, 3.1 mention:
" Local Num  Identifiers assigned by an RIR (or LIR) for each /48 as
               allocated to an end site or user.  It is expected that
               allocations by an RIR to an LIR will be in blocks of 1000
               consecutive Local Nums, to amortize administrative workload."

which again give us some sort of aggregation... is this something we want? 
(althought it would fit us, where I work, perfectly since we would get 
almost all the space we need quite easy:-)

But then again 5.5 say it is recommanded to not allocate aligned blocks...

maybe clean up the wording on those part a bit?
