Are there still people who deny that SM and WW have something in common after Patty Jenkins spent all of her film's promotion talking about their similarities?
Speaking of Patty's movie... after watching it, there were also people, a lot of people, who saw Diana as more true to Superman's spirit than Cavill's character, and begging for Patty to direct the next Superman movie. That was a majority compared to the people in denial that you refer to.
Even if they aren't among the main characters in the series, these little gestures like Diana touching Clark's hand, etc, show to those familiar with the source material that their closeness have been respected by the people who made the show.
We'll see if we'll get other brief moments like these ones when the series returns.
