I think this is going to still cause issues with dependencies, 
which might just be a dub problem but I'm not sure.

For example I've tried to add `dflags `-preview=safer` to my 
dub.sdl and now I get errors from 3rd party libraries:

```
lib\bindbc-glfw\source\bindbc\glfw\binddynamic.d(326,24): Error: 
`name.ptr` cannot be used in `@safe` code, use `&name[0]` instead
lib\bindbc-glfw\source\bindbc\glfw\binddynamic.d(342,33): Error: 
`@safe` function `loadGLFW` cannot access `__gshared` data 
`glfwInit`

```

Still it's a great step forward, thanks for your work~
