Interesting they're adding new support for DTLS 1.3 when afaict most new applications are defaulting to QUIC datagram mode. I have something built around DTLS 1.3 and am using wolfssl for that reason, will have to check this out.

QUIC for embedded? I haven’t seen that, but there is a lot of DTLS. Particularly with 1.3, it makes QUIC look like a behemoth in code.
