Not necessarily. If you generate a random pile of bits for the identifier and
use that identifier on the local machine - even printing it to the screen for
example, which ping could do - and then capture those same ICMP echo
request/response packets using those random pile of bits for the identifier
field, it would nice if they matched.

This I agree with. The fact is that we are stuck with ICMP packets using both
big and little-endian identifier and sequence number fields with no reliable
method of accurately determining the endian. Which is why I gave up on trying
to add some heuristics.
Unless someone disagrees, I think this bug could be closed now?
