This uses *certificate_type extension, which is well-known to be 
extremely poor match for TLS 1.3. And for application like this, 
one wants something that is usable with TLS 1.3. 

Furthermore, it doesn't specify how the certificate message is 
interpretted. 


Also, as of currently, the highest ECC performance in TLS 
is X25519 for key exchange and Ed25519 for authentication.
