The situaion is very similar to the last /8 situation and I would support extending the last /8 policy to 16 bit AS numbers as well.
Actually, it is totally different. LIRs are entities that handle address distribution, but not necessarily run a network (many do, some do not), so tieing "last /8 address space" to "one LIR one block" is a compromise that sort of follows what the LIR does: hand out address space. Now, AS numbers are much more tied to the structure of the network - who is running BGP, who is transitting other ASes or just a leaf node - and the model "one LIR = one transit autonomous system" totally doesn't hold - not even "one LIR = one autonomous system in BGP". For a leaf node, 32bit ASes work mostly well. For a transit network, not so much, for the reasons listed - but not every LIR is a transit network (or has plans to eventually become one).
