Hi Jorge As defined in RFC 8584 AC-DF and HRW are independent of each other.
RFC 8584 updates RFC 7432, however RFC 7432 bis does not update any aspect of RFC 8584 including HRW as you stated. I would think HRW would be the new default algorithm used for DF election and would not be a knob as it fixes the major deficiencies with the modulus algorithm.
