I encountered this issue while testing quinn during interop.  client kept retransmitting Handshake but server had already dropped handshake key.  The problem is that server starts timer too soon; client has no way to know that handshake is received by server and it started timer.
My preference is to have a explicit signal from server.  It is much better to doing something complicated using ACKs.
