Comment (by yawning):

 >  100% of the failures used a fingerprint with TLSv1.3, while only 28% of
 the successes did. I haven't dug deeper to see what the difference between
 the success and failure TLSv1.3 handshakes is.

 The kludges inherited from `crypto/tls` only apply when TLS 1.3 is
 requested.

 networking/utls/blob/master/handshake_client_tls13.go#L300

 networking/utls/blob/master/handshake_client_tls13.go#L215

 Making the library support the NIST curves is trivial, and would fix this
 problem.
