Okay, did just find this:
Looks like the C7's zwave chipset forces it.
With the exception of a pair of zigbee bulbs not reporting their state, things are much better after pulling the inovelli bulb out. Hubitat support emailed me a few hours ago and said they pulled that bulb from compatibility list for the C7. I'd suspect a secondary controller might resolve this issue as well. It just doesn't seem like something that I should have to purchace for a brand new hub. I'll probably hold off for now, since it's gotten better.
