SCRAM-SHA-1(-PLUS) + SCRAM-SHA-256(-PLUS) + SCRAM-SHA-512(-PLUS) supports
"When using the SASL SCRAM mechanism, the SCRAM-SHA-256-PLUS variant SHOULD be preferred over the SCRAM-SHA-256 variant, and SHA-256 variants [RFC7677] SHOULD be preferred over SHA-1 variants [RFC5802]".
Can you add support for?

@mawis: Have you progressed on it?
Note: SCRAM-SHA-512(-PLUS) + SCRAM-SHA3-512(-PLUS) + 2FA are new.
