It also fits better with STUN where the hash algorithm (SHA-1 and now SHA256) has been split off the password hash algorithm (MD5) from the beginning.  draft-yusef-sipcore-digest-scheme does not even talk about the password algorithm, continuing the (I think) rather bad idea of linking the two together.
