I wouldn't get my hopes up on this matter.
- Hubitat seems to have lost interest in the Zigbee ecosystem: install codes, green power, pairing issue with IKEA battery devices, etc. Also, if you complain a Zigbee 3 device does not work with C-7 (e.g. Shelly Gen4 devices), you'll probably get back a response along the lines of "Zigbee 3 devices should be backwards-compatible with ZHA 1.2, so it's the device fault".
- Shelly has no reason to invest time and money in supporting a ZHA 1.2 device; I wouldn't if I were them
Anyway, I recently jumped ship to Z2M and I'm shiny! Maybe Hubitat will put Z2M into C-9 like they did with Z-Wave JS (if they keep a Zigbee antenna, that is).
