Well, I could easily add this attribute to the list instead.
I think that 64 "pointers" in the network was just a mistake of protocol 1.
They means messages are more than 4gb but they are contained (even on protocol 1) in 4gb as message size is 4 bytes. And supporting more bytes would mean that we should allocate lot of memory as we store entire message in memory. Probably somebody could use these sizes (even 32 bit) to force allocation of huge memory (on both client and servers) causing possibly some DoS.
