I was just saying maybe WSL shouldn't be advertised as ready for prime time without SECCOMP-BPF support implemented, e.g: for OpenSSH pre-auth sandbox. At least not in roles where security is paramount.
Also, remember that our primary goal for WSL right now is to provide a local development environment in which you can build, run, and test *NIX code.
