Yes, it has. And can still lead to confusion, in certain instances.

I'm not trying to convince you, or anyone else, to write or speak the way I do. And I'm amenable to any specific person or group of persons representing their (<- there's one!) own interests telling me how to describe them. But I'm not particularly interested in etymological diatribes; I've seen them all and understand the arguments. I have made my decisions, and will continue to make my decisions, with all of those arguments in mind. Rest assured that you have nothing to gain by advocating them to me, as a third-party trying to police writing. I use "they" singularly, all the time, just like everyone else. And I use "ne" when I'm specifically acknowledging that I don't know the preferred pronouns, and have been left to fill them in using my own standards.

This isn’t about you. We speak English on this forum, in fact it’s a requirement, please use it.

I'm sorry that you think you have a say in that. But I'll speak however I want to. Your criticism on this matter means nothing to me, so fire away.
