The problem is that all popular running implementations (BSD, Linux
etc.,) have difficulties interpreting the RFC 1122 language in the way
it is supposed to be interpreted which can lead to DOS scenario if
properly not mitigated. That is the whole reason of coming up with this
short draft. All these were discussed in the WG and the rough consensus
of the WG was that it is ok to have this clarified in the form of a
document. If there is anything that needs to be re-worded etc., to make
this clear, we can address that.

Thanks,
