Historically, and until recently, --extra-small produced a usable build. When I recently made osrouter be modular in 39e35379d41fc788 (which is useful in, say, tsnet builds) after also making netstack modular, that meant --min now lacked both netstack support for routing and system support for routing, making no way to get packets into wireguard. That's not a nice default to users. (we've documented build_dist.sh in our KB) Restore --extra-small to making a usable build, and add --min for benchmarking purposes.
