By using non-square dots, wider, you need less horizontal dots to encode. The original DVD/TV format uses that. 704 dots are displayed at a width of 1024, at least in Europe. I think is the US 720 is displayed at 854. https://trac.handbrake.fr/wiki/AnamorphicGuide

If you want to play it on a standard-format DVD of course not, but if on a standard BD player or other media player as Roku/AppleTV etc I would say give it a try and see for your self.
