I don't think that is true in general. At least for most current server class and older desktop and laptop class systems they use the same format factors and enclosures, although they are slightly divering now. So I think this needs to be quirked based on the platform and/or enclosure. I don't have ATA SSDs any more, but at least in my laptops the NVMe SSDs do see unsafe shutdowns during reboots.
