@marten-seemann well in that case, the source of the problem is the retransmission algorithm, not this. Why does it make sense to not retransmit 1-RTT data when there is an outstanding CFIN?

Just consider the simple case where the client's second flight (CFIN + some data) is lost. When the PTO expires, you should resend all of that.
