When I built the tabs for the Device page, and then used a similar pattern for the Deployment page, I quickly learnt that LiveComponents have a lot of quicks which lead to confusing code and duplicated state between the parent and child component.
For example, LiveComponents can't subscribe to topic, listen for pubsub messages, or respond to timer events.
I recently discovered a better path forward which uses LiveView hooks : https://hexdocs.pm/phoenix_live_view/Phoenix.LiveView.html#attach_hook/4
I've created some reusable code for implementing the same pattern with the Deployment page, and the upcoming Org pages.
