So write a BCP that amends RFC2821. This HAS been done before. When =
directed broadcasts were the hot new way to cause damage, RFC 2644 was =
born (a.k.a. BCP34). It simply said that since the original document was =
written, it had been determined that a required default setting was =
found to damage the Internet and that henceforth, the default value MUST =
be the opposite. The option is still there for those cases when needed, =
but damage is avoided. Those coding up new router stacks hopefully =
heeded the advice. Certainly two of the leading vendors at the time did =
so.
Instead of saying "well, it's obvious to everyone," do something about =
it.
