as a gender neutral pronoun such as in your first example.

I'm not crazy about it for a specific individual, because it's still a collective/plural pronoun.

As for that weird list you've given, I haven't run into any of those. They look like an alternative version of German or perhaps one of the Scandinavian languages. Our pronouns don't need to be that completely re-invented. Plus, I am certain that there would be someone who would insist in the series starting with Z, and someone else who otherwise seems to be of the same gender, insisting on one of the others. I also keep on hearing of people who claim not to identify full time with one gender, but go back and forth, and who then get angry when others cannot read their mind about what they feel like on a particular day.
