I wasn't implying a full node for every light client, of course that doesn't make sense. People using light clients in their products, like a wallet or DApp, are probably adding tens to thousands of light clients. When you add that load to the network, you should also deploy a few full nodes, and probably add them as static peers if you want the application to work well.
