This was already the case, right? Previously, there were all these controllers (disk, I/O, cooling, etc) running only-god-knows-what-firmware from only-god-knows-who vendors, and now that's all been rolled up into a single integrated thing.
I could see an argument that this is a bit of a security concern: "There is now one God-level firmware unit with multiple possible attack vectors! Own the USB controller, and get access to the disk controller for free because they're on the same chip..." but it's not clear to me that this would be worse than what we already had...
