At this point, publishing the scrypt document is about documenting reality. Scrypt is already widely deployed used on the Internet. That is why I believe it is useful to publish this. I agree it is better to promote Argon2 going forward -- and that work is in progress -- but I believe there will be years until it reaches the same deployment level as scrypt. Argon2 was finalized only on the last months. /Simon
