Well, sub-allocation used to be special in the same way allocations are
different than PI assignments - "the receipient is assumed to be an
ISP-ish operation that provides (needs-based) assignment to lots of 
end-users".

There are traces of needs-based still present in the system - like the
transfer policy requiring the receipient to "document need" to the NCC
to get the transfer approved (... and the ARIN folks flatly refusing 
cross-RIR transfers if the receipient RIR has no needs-based component).

So if you permit LIRs to "just give away their stuff" and then go back
to the NCC and claim "need!" (to get an incoming transfer approved),
this is not without its own risks.

(Not that we couldn't change the transfer policy towards "both parties
tell the NCC, the NCC registers the transfer, done"... someone would
have to propose that, though, and fight for it)
