Another way to see it is that he/him/his are always gender neutral, and only the feminine forms are gendered for clarity when context calls for it. Most often context does not, which could be why you’ll so regularly hear all-women groups referring to each other as “guys”.
Millennia of human societal development doesn’t care about the enlightened PC arrogance of 2019.
Sure, there are reasons why having gendered pronouns at all can be bothersome in today’s world. There is some merit to the idea of doing away with them, but you can’t force cultural change on human beings. Even if we move to gender neutral pronouns, the zeitgeist would most likely simply revert to he/his/him like it always has, rather than some contrived “xe” or similar such.
