By the way, I am currently implementing ClientHello recording (RFC 8446 8.2), as anti-replay measure. That suggests that in some occasions (e.g. a ticket arrived out of time window), the server should reject 0-RTT but can continue with 1-RTT. In that case, the client may want to resend the early data as a normal application data after handshake. So rather than having a separate send function (`gnutls_record_send_early_data`), it might make more sense to reuse `gnutls_record_send2` and allow it to fallback from 0-RTT to 1-RTT.
What do you think?
