Associating the desire of NVMe vendors to allow users to ship down eBPF programs to run on the device and XRP is a major mistake in the article. XRP has nothing to do with what the NVMe vendors want to do, and XRP is a pure kernel solution that doesn't need any participation from NVMe vendors. I think it's unclear whether XRP even has real value - it certainly may, but I believe the benchmarking in the paper was deeply flawed[1].
