Use case; I want to run a local server that's not\barely exposed to the public internet. Via shadowsocks I would be able to connect to the local network of the shadowsocks server. Currently this is completely blocked via https://github.com/Jigsaw-Code/outline-ss-server/blob/3c2b0f160b2f759ea6eb3d35df6897404bd86e09/net/private_net.go#L36
