I have about a dozen of the generation 3 bulbs (the ones with bluetooth) that are Zigbee 3.0 directly paired to my hub and they appear to be solid repeaters in the Zigbee network. I believe the advice for Hue bulbs dates back to the older generation that were ZLL and not 3.0.
If you do want to pair them with Hubitat, you may want to try my Hue driver available from HPM ([RELEASE] Philips Hue Zigbee Driver (not using Hue Bridge)) While I've not tested specifically with the ceiling light fixtures, I see no reason why the color temperature driver would not work. The main advantages are push updates (no polling for the Zigbee 3 generation) and support for level and color temperature staging while off.
