If DSN was shot with DSN in mind, I would be happy. If it was shot that way you could make a case that was the way it was meant to be seen. I've hada widescreen TV's since the mid-late 1990's. I believe Europe was quicker to adopt Widscreen TV's than the USA.
And I would disagree that 15 years ago consumers had to fight studio ignorance from cropping movies to 4x3. My memory might be faulty but I could walk into a store and easily buy a Widscreen VHS/DVD true some movies were also released in 4x3 format. But that might be down to my point above.
