Too early to adopt

Why: Smallest sizes in the field are attractive for bandwidth-bound signing, but unstandardized Round-3 status, no constant-time signing, signing that is explicitly not timing-side-channel-secure, and a demonstrated key-recovery power-analysis attack make it unfit for the financial/signature path. Compactness alone does not clear the protected-component bar.
Next: Track the NIST additional-signatures Round 3 outcome (tweaks due 14 Aug 2026) and the SPA/constant-time cryptanalysis line; do NOT touch Rule #29 protected crypto. Keep ML-DSA-65 as the hybrid signature primitive per Rule #2.
