All the hoop-jumping I can think of is open-source. https://github.com/tailscale/go https://github.com/tailscale/go has the Go toolchain changes for size reduction (though most get upstreamed), and the rest of the size reduction stuff comes from lazy configuration, i.e. keeping as little idle state as possible. But that's useful for memory reduction on all platforms, so it's just in the general network engine at https://github.com/tailscale/tailscale https://github.com/tailscale/tailscale .
