Thing is that OF for PCIe devices is already a thing so NVMe already
have OF support. And that is totally OK if the PCIe is not removable.

So it's really a simple subnode to keep things organized in DT and
permit common code. Why this would be problematic, the implications of
adding support for this are really none, only additional support for the
new devices that are taking this path. (you would be surprised by the
amount of hacks they use downstream so about times to stabilize this the
correct way)

The emmc one and also nand attached to spi. They all follow this.

controller {
	card {
