My 5 cents. For the IoT environment this ciphersuite is not very useful. If you want the best possible performance, lowest RAM utilization and use as little flash as possible then you go for a plain PSK ciphersuite (without DH/ECDHE). If you are already paying the price of the asymmetric crypto

Just to make note on-list, I support adoption of the draft. I've already cited it in the current TLS 1.3 draft as a normative reference, and thus consider it required for completion of the new version. One objection to part of the current draft, though, which I think needs changing. It currentl
