I'm glad it's been insightful! At the end of the day, my original post was primarily to offer insight based on how I personally experienced the situation as a trans woman. The fact that it also gave me the chance to make a suggestion to the developer as well, was just a wonderful case of feeding two birds with one scone, haha.
It's something most cis people just don't even consider, which is entirely fair! I can't blame cis people for not consciously thinking about how trans people view the world around them. Expecting that would be just as unfair as expecting non-blind people to actively think about the way blind people experience the world around them. Granted I'm not blind, so I obviously fall in the same category of not considering those things unless I'm actively given a reason to consider them.
And as the developer themselves said, they hadn't really put a lot of thought into the body/voice and pronoun situation themselves, as those things were initially added for the sake of development if I recall their post correctly. So the fact that those elements of the game can now potentially be used to tell a minor story of their own, that's just a happy coincidence born from me broaching the subject in my initial post.
