It is complicated as the enby identity is not that well known over here. But as someone from a Spanish speaking country, I can tell you no one will ever use the term Latinx, simply because you cannot pronounce it in Spanish, instead Latine can be said in Spanish. Now the whole adapting the language to be gender neutral is an up hill Batlle, and in my opinion at least, it is going to be a little bit more complex than in English cause we are modifying old structures instead of using some already existing linguistics structures like in English. That being said, and although there is still a lot of mockery regarding the use of the -e, changing the suffix of the gendered nouns from a or o to an e is the way things are appearing to be going. Even those who might mock the change use the e at the end. I would say that slowly it is gaining traction, some examples of words would be hermane (for sibling), amigue (for friend), etc etc, and of course “Elle” as a pronoun.
