Insanity. No language can function with a separate pronoun for each person. Language functions in generalities, with one pronoun for men, one for women, and another for things.
It is impossible to have a system in which each person has a unique pronoun. No one can remember all the pronouns. The moment someone uses the “wrong” pronoun, the fascist police swoop down and arrest him.
“They” is not inclusive and flexible. They is for more than one person or thing.
I have a solution: each person already has a unique designator: his or her name. So, instead of referring to a person with a pronoun, we simply use his or her name. So you never need to remember if that one “uses” “zey,” “zot,” “zim,” “zer,” or whatever the hell else they invented.
The moment someone uses the wrong pronoun, the fascist police swoop down and arrest him.
Thats the whole point.

The best solution,or rather palliative, for this foolishness is to adopt a foreign word, as usual in English.
There are lots of genderless languages. Most of Southeast Asia for instance speaks some Austronesian tongue, which are all genderless.
In the US the most widely spoken of these is Tagalog (Filipino). The personal pronoun is “siya”, plural “sila”. It is proper to go borrow that word.
Looking deeper, the idea that a genderless language changes the concept of gender in a society is easily disproven by taking a look at societies that use genderless languages.
