I would take it a step further. I want a date on any kind of article, scientific or not. Bonus points for having separate published and last modified dates.
Having a date on the article is not an advantage here.
Unfortunately I don't see this going away anytime soon. Something like a browser plugin that notified you of article date could be helpful, but would face challenges in mass adoption.
Have you noticed the general reduction in usefulness/efficiency of web pages? I sure have. Pages turn a 100 word answer into a 10,000 word essay with 5 videos.
