nice idea. recently in discord #russian channel someone asked that he used mode: 'static' and was wondering why it dont generate static html files :)

@aldarund I was also caught in this pitfall when I was trying out new modern mode. For some reason I decided that it should be specified like mode: 'modern' and since I didn't get any warnings/nor errors during the build - I was convinced that it's the right way to go, although nothing been working in the browser. It just was an endless wait for the response
