the Aqara Zigbee 3.0 devices?, where exactly are these available? BTW alibaba and the like or direct from China don't count as available for most people, including me.
So if you want to loan them to me, I'll write/verify drivers for them...
There is nothing in the Zigbee 3.0 spec that would guarantee a better routing/mesh experience...
and anyone that thinks certification guarantees proper functionality just hasn't been exposed to many devices, Zigbee or Z-Wave...
