Other. Document that some networks drop fragments, the reasons why they do
so, and the impact on applications, but provide no advice.

It's unlikely that this group, let alone the IETF, would agree on what

of an operations group to document real operational issues, so the rest of
the community, including application developers and protocol developers,
can be made aware of it.
