IIUC, all except 3 of those bugs, are issues from the device fuzzer. It is nice that we find those, but if we don't consider this a device targetted at virtualization use cases, I don't think they're a reason to remove the device. > Having hardly any knowledge about this device and its usage at all, I wonder > how much it is still used out there in the wild?

We've got countless NIC models in QEMU most of which have minimal users, are possibly buggy, not actively maintained, but exist to support non-virtualization use cases. We've especially not had "how many users are there" as a criteria for acceptance or removal of a device.
