Small nitpick: LWSP is defined (informationally) but not used.
For key types/algorithm strings, we have key type "rsa" for algorithm
"rsa-sha256", similar for ed25519.
But somehow, for the PQ hybrid, "sha512" is suffixed to the _key type_
too? Aren't the key types agnostic/orthogonal to the hash function?
So shouldn't the key type (DNS k=) be "mldsa44-ed25519" (but the
algorithm part in s= in DKIM2-Signature be "mldsa44-ed25519-sha512")?

Internet-Draft draft-ietf-dkim-dkim2-dns-01.txt is now available.
It is a work
item of the Domain Keys Identified Mail (DKIM) WG of the IETF.
Title: Domain Name Specification for DKIM2
Author: Wei Chuang
Name: draft-ietf-dkim-dkim2-dns-01.txt
Pages: 16
Dates: 2026-10-17
Abstract:
The updated DomainKeys Identified Mail (DKIM2) permits an
organization that owns the signing domain to claim some
responsibility for a message by associating the domain with the
message through a digital signature. This is done by publishing to
Domain Name Service (DNS) of the domain a public key that is then
associated to the domain and where messages can be signed by the
corresponding private key. Assertion of responsibility is
validated
through a cryptographic signature and by querying the Signer's
domain
directly to retrieve the appropriate public key. This document
describes DKIM2 DNS record format and how to find the record.
