Oh believe me that did not escape my notice. They made that clear in the post as part of the focus. They didn’t simply say her designer, but choose to bring focus to her gender. Which in and of itself can cause issues. On one hand it shows that females play important roles in game decisions for SSB4. But it can also be taken as a marketing ploy or focus as if to defend any sexism. The idea that women can’t add to sexist ideas is false. Women can contribute to harmful views of women. That’s why this can get sticky.
I personally feel and hope that it is as you say.
