Isn't this the whole point of Thread? You have a low power mesh network for inside a deployment (house, office, factory, whatever) and it's the border router which does the "communicate with the internet/lan/wider network" piece. These are typically plugged in (so no worries about having to be low power) have plenty of memory (so no worries about having to drop established routes like a router).
