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

While your draft is rather harmful than useless, I'm fine
if the following point of the draft:
>> Originating sources MAY set the IPv4 ID field of atomic
datagrams to any value.
is changed to:
>> Originating sources MUST set the IPv4 ID field of atomic
datagrams to values as unique as possible.
which is what the current BSD implementations do.
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.
