In version -08 we added the following text:

8.2.  Password/Passphrase Comparison

   In systems that conform to modern best practices for security,
   verification of passwords during authentication will not use the
   comparison defined in Section 4.2.3.  Instead, because the system
   performs cryptographic calculations to verify the password, it will
   prepare the password as defined in Section 4.2.1 and enforce the
   rules as defined in Section 4.2.2 before performing the relevant
   calculations.

That's a good suggestion - we'll incorporate that change in the
post-IESG revision.
