Far from it, sequential IO optimization isn't dead. Sequential reads need to be optimized to produce optimal performance for selected workload. That usually means applying a lower level of inline compression. In some cases deduplication works better before, in other after, compression. Sometimes post-process dedupe is more suitable than inline. Then there's erasure coding and data protection methods that are still being optimized for NVMe with sequential workloads, including random workloads which are being sequentialized to work better with latest flash media. I would even say developments in sequential IO are becoming more important than random IO.
