This means that when my DVD-DW drive needs a firmware upgrade I should be able to apply that upgrade without having to connect the drive to another computer that happens to be running Windows because the manufacturer (I'm looking at YOU Samsung) supplies the upgrade program as a Windows executable
This is what fwupd.org is trying to solve - its not quite there yet, but the idea is that with a modern UEFI based machine, you can get firmware updates delivered to Linux machines without any hassle. Unfortunately its mainly the big vendors at the moment - great if you have a Dell or a Lenovo device, every bit of built in hardware will have its firmware covered. Looking at their database, the only firmware Samsung push to it are for NVME devices.
