Animate/inanimate noun class distinctions aren't unheard of in language, but I don't think they'll manage that one haha. Afaik flora typically fall on the inanimate side too. Maybe if they advocate for it as part of a push for veganism, anti climate change, animal rights.

It still wouldn't be the weirdest thing in the history of English pronouns. I'll never be over English borrowing they/them from the Norse. It's extremely uncommon for languages to borrow function words (pronouns, prepositions, etc), it's very interesting that they/them stuck.
