Beyond what Russ just pointed out, I find the first line to be in bad taste. Any IETF spec that says "you must not be able to verify a signature even though it is valid" is pretty offensive.

How about adding a "MUST warn the user that key is too damn short to be considered safe, even though the signature is valid" clause instead?
