I will include a response to the rest of this in my summary of the last call concerns. Regarding your last point:

There are implementations that set DF=1 and ID=0 (cellphones). BSD does not make IDs as unique as possible; it selects them according to a pseudorandom algorithm that does not take into account the datagram's source IP, destination IP, or protocol. I.e., BSD code repeats the IDs more frequently than necessary when a host concurrently sources datagrams with different (srcIP, dstIP, proto) tuples. So it would already be in violation of your proposed wording, as would most ID generation mechanisms. Joe
