Do we need the trailing slashes? To my knowledge not having a trailing slash is best practice, although I acknowledge that in this age it is mostly a matter of preference.

Personally the determination I'd use for that is: does the website fight you? Without a trailing slash you get redirected to have the trailing slash.
