WiFi extender in bulbs

Reading about the weak network, network problems so many people are having setting up a Wyze integration,
building a bulb with wifi extender would be nice.

imagine the cost and space associated, let alone the extra heat generation.
IMO not practical.
However, you could get some of that IF you were willing to use Zigbee protocols, they mesh network inherently.
Personally do not want another layer of protocols and lag associated.
