I'm nervous about what this means for the future of nginx's built in load balancing. That's been an important and rock-solid part of my infrastructure.
Throwing out a question to the room: if the worst happens and Nginx gets butchered, would it be so bad to go back to using Apache? I've never used it really, everything I've done has been Nginx, but is there some technical reason why Apache wouldn't be a fine fallback option for an open-source server?
Apache is really struggling on resource consumption. It's still living in the world of one process or one thread per connection.
Operationally it always ends up in a clusterfuck of rewrite rules and there are many gotchas with undocumented and misbehaving directives.
