SYN flooding is a specific instance of "have to hold too much state" whereas
the reason for not considering TCP mandatory is the general form of "have to
hold too much state".  also note, the operators of those nameservers aren't
reading [email protected], or indeed any other mailing list where they could all be
reached.  the installed base is, as usual, an impediment to righteous change.
