A device that supports append is completely usable for those customers,

Not really. You know as well as I do that some features are disabled for
a particular SSD model on customer requirements. Generic models
implementing append can submit both I/Os, but those that remove append
are left out.

I would like to understand how we can enable these NVMe-compatible
models in Linux. If it is a performance concern, we will address it.
