No, this specifically is about gender swapping characters. Diversity in characters in games as a whole is on the rise recently, and that's great. But you can't have a LoZ topic anymore without someone chiming in about how great Girl Link would be, and to me that's dumb. It's the absolute laziest way to go about representing women in a series full of female characters just begging for their own share of the spotlight.
I don't like the idea that everything has to be designed to appeal to everybody, anyway. And LoZ really is a series that hasn't exactly had a problem attracting female fans in the first place.
This is what it comes down to.
Given the frequency of the request for a female Link, most people don't consider the character or identity of Link to be related to his gender. Link is simply green clothes and a sword used as the vehicle for a Zelda adventure. Lots of people actually like Link, too.
So when people think a female playable character in a Zelda game, a female Link is at the top of the list of options. Because for however unnatural it might seem to you, it's a natural and organic leap for (most?) others. They like Link, but also want a female avatar, so a female Link becomes the go-to for what is a more abstract request for a playable female.
However, if in the next Zelda game, you could choose between playing as Link or a new female avatar named Kori, these same people would be happy. Or if you actually played as Zelda in the next Zelda game, these same people would be happy. Just because "female Link" seems like the shortest distance between two points doesn't mean it's the only path.
So, generally, the people saying they want a female Link and the people saying they want a new/existing female character to lead the next game are arguing the same thing: female protagonists. How each group is arriving at their interpretation of that theoretical character is merely a difference of whether they view Link as a pair of green clothes or a bloodline of young men.
