Language changes over time. Sometimes it’s a slow gradual adoption of new terms, sometimes it’s a cool new slang, and sometimes it’s word policing. I understand that, historically, a certain type of person would use the word “females” instead of “women”, but I can see a shift happening where there number of people using the word “female” is on the increase. Let’s say you’re having a conversation and specifically want to refer to female people - you can’t actually use the word women, which used to imply “female” but now includes males who transition. So depending on context, and what you need to communicate, the word female can be absolutely critical, whereas the word woman may not suffice.
