Cryptographic standards should be judged on their merits, not on the=20
bureaucratic difficulties in changing them. Specs have been amended=20
before. Even NSA was willing to revise its original secure hash=20
standard. That's why we have SHA1. If I am right and WPA needlessly=20
introduces a significant denial of service vulnerability, then it=20
should be fixed. If I am wrong, no change is needed of course.
