It does, but I believe this behavior is specific to Intel Skylake (and presumably, later) hardware. Matthew has a few details at the URL I included earlier, as well as one of his previous blog entries.
The problem isn't that Linux doesn't recognize the RAID data, it's that the controller switches to an unrecognized and undocumented PCI ID, for which there are currently no Linux drivers. Linux won't even see the storage device, because it can't operate the controller that the storage device is connected to (while it's in "RAID" mode).
