I agree, that this looks like a bug.

On my NetBSD system:
% gnutls-cli -l | grep -i tls1.3
TLS_AES_128_GCM_SHA256 0x13, 0x01 TLS1.3
TLS_AES_256_GCM_SHA384 0x13, 0x02 TLS1.3
TLS_CHACHA20_POLY1305_SHA256 0x13, 0x03 TLS1.3
TLS_AES_128_CCM_SHA256 0x13, 0x04 TLS1.3
TLS_AES_128_CCM_8_SHA256 0x13, 0x05 TLS1.3
Protocols: VERS-TLS1.0, VERS-TLS1.1, VERS-TLS1.2, VERS-TLS1.3, VERS-DTLS0.9,
VERS-DTLS1.0, VERS-DTLS1.2
This output is identical to the output I get on my GNU/Linux system
where the system does not exist. So I'd assume the TLS 1.3 support does
not differ...
Thanks for your support,
sascha
