There are SO MANY changes to be made for constrained devices. Just a couple quickies, certificate order is all backwards. Eliminate basically all use of DER, preferring CBOR instead. Define larger coarse protocol presets instead of dozens of optional extension points. Also TLS has no certificate caching, which for some radios is nearly fatal and will be a major issue with embedded and PQC. Etc..
