I finally got rid of all my Smart Lighting rules, having finally gotten the last devices moved over to my C-7 and everything recreated in the Motion Lighting App. The Smart Lighting outage last week was the last straw that got me to moved all the computer area (office) lights over.
I still have 60 Zigbee devices (including 40 Iris contact sensors; one on every window and door) to move over. But that is passively monitored and not part of any automation. Those will move over in the coming week.
