I understand the redirecting to non-www is subjective, however I find less characters in the URL is cleaner. Also for a majority of my projects cookies are not used, so it is not a big deal to use a non-www base url.(Static blogs and simple vanilla sites for various school projects, etc).
Also as far as foo.com/ -> foo.com, I was referring to the URL, not the acutal path.
example: https://www.google.com/ redirects to https://www.google.com correct? Maybe I am missing something...
