 QUIC takes the unprotected content of TLS handshake records as the content of
 CRYPTO frames. TLS record protection is not used by QUIC. QUIC assembles
 CRYPTO frames into QUIC packets, which are protected using QUIC packet
 protection.
 
+QUIC is only capable of conveying TLS handshake records in CRYPTO frames.  TLS
+alerts are turned into QUIC CONNECTION_CLOSE error codes; see {{tls-errors}}.
+TLS application data and other message types cannot be carried by QUIC at any
+encryption level and can be treated as an error if they are received.

How would it look like if they were received?
Wasn't @martinduke's point that QUIC doesn't even provide a way to send them at all, since there are no record headers?
