I think just allowing a server to detect whether the connection is still in fast-open state should be enough. If the server sees a non-idempotent request it can make sure the initial ACK has arrived before proceeding. Make it detectable by say making {aio_,}fsync not complete until it's arrived, or fabricating a redundant EPOLLOUT edge.
