And maybe that's fine because it isn't a signal of ideology like "pregnant person" is. Don't forget that if scientists were using these terms, they were likely already doing so because of political pressure, so it is good to stop it in cases where it's nothing to do with their research (eg. transgender parturients). Of course it doesn't mean this order isn't ham-fisted, but research is often polluted by politics because it helps get funding as well as researchers are pretty politically biased in some fields.
