I would use it and recommend it to people I know, as I already do.
But how about no browser at all? How about I use my own video player to watch a file I received over network?
We have essentially operating systems(web browsers) with pipelines, processes and sandboxing just to be completely ignored by websites which instead shove a message "install our app" down our throat.
Impossible. Look at what your memory usage in a browser goes to (about:memory). Most of it is DOM/JS, images, media, etc.: things that are used by well over 90% of pages.
