RFC 8684 says:
If the token is unknown or the host wants to refuse subflow establishment

the receiver will send back a reset (RST) signal, analogous to an unknown
port in TCP, containing an MP_TCPRST option (Section 3.6) with an
"MPTCP specific error" reason code.

mptcp-next doesn't support MP_TCPRST yet, this can be added in another
change.
