I think it would be cleaner to make it a union, but I don't care that strongly. But we probably want a way to distinguish which one is supported. E.g. for SCSI we set a net BLK_FEAT_WRITE_HINTS, for NVMe we'll set BLK_FEAT_STREAM_SEPARATION. Either way this should probably be the first patch in the series.
