This situation really highlights the importance of discourse with issues like this, and the necessity in confronting development teams and corporations on their direction. It's a reminder that while it's easy to brand entire corporations as transphobic/bigoted/racist/etc (and I'm not contesting any specific incident of this), it's also important to remember that most games these days are developed by an enormous bastion of individuals of varied perspectives and beliefs, many of which are doubtlessly "allied" against what might seem like corporate level shortsightedness and bias.
Continuing the conversation and expressing the need for change can, in the right cases, spark conversation within these groups where the people who are your allies are given a more prominent voice. It gives them opportunity to confront the absence of features they feel would make the experience more inclusive, and the open discourse within the community encourages senior decision makers to see from a perspective they might otherwise not have.
Obviously proof is in execution and, like I said in my previous post, I don't expect this to at best be anything more than having the options to play as a trans / nonbinary character and the game to flow accordingly. But the conversation sparking at CDPR because of the open discourse and critique elsewhere, and them stating they will make an effort to include these features, is exactly the point.
It might be late in development, but it happening in a AAA title gives voice not just to the trans / nonbinary community, but the developers at CDPR who've felt this content should be included and are now in a position to see it through.
