Nah... The /64 thing is fine. If they hadn't done that, we likely would have only a 64-bit address space total. 64-bit lans with 64-bit routing identifiers are fine. What would be nice would be if we changed the semantics a bit and made it 16+48+64 where the first 16 of the dest+source could be re-assembled into the destination ASN for the packet and the remaining 48 identified a particular subnet globally with 64 for the host. Unfortunately, that ship has probably sailed.
Stateless autoconfig works very well, It would be just perfect if the network boundary was configurable (like say /64 if you really want it, or /80 - /96 for the rest of us)
There really is no need for anything smaller than /64. What, exactly, do you think you gain from a smaller netmask? Owen
