You want to know something silly? There are multiple versions of go-bindata floating around in the world, and they have different features and flags. This httpfs package was written with https://github.com/go-bindata/go-bindata and uses the -fs flag. Most everyone else (nixpkgs, homebrew) seems to have moved over to this fork https://github.com/kevinburke/go-bindata, which does not have that feature. Run `go generate` with this installed and you'll get an error like `flag provided but not defined: -fs`. It looks like `httpfs` is the odd one out here, and it's not used anywhere I can find either here or waypoint, so let's just remove it so we can `go generate` cleanly with the version of go-bindata that most people are using.
