Elephant in the room is, that this none of this is relevant nor will it ever catch much traction.
Afair the gender star *Innen got officially introduced in university writing codification, although the 'doctrine' should still be, that you should gender - so even using the old Binnen-I (SomethingInnen) should be fine, and if you don't gender at all, afair there shouldnt be repercussions either.
Outside of the university level you don't see it anywhere - and none of it should get traction outside the realm of academia/public administration. Watched a bunch of Chomsky recently, so I use his argument. In linguistics there seems to be a grammatical structure hardbaked into/discerning from the way we learn languages. Previous attempts at introducing formal language that circumvented that (in terms of grammatical structure) all failed (to essentially garner any traction).
While those elongated words in the german language are a 'known feature' of that language, the amount of repetition you'd have to go through, if you follow all of those rules, alone should make it entirely impossible that this will be picked up in a broader fashion.
And this is something we know for quite some time, stuff gets developed/dreamed up at the university level - and to then get it adopted by society at large - it first is pushed as mandatory, where you can convince institutions - but to ultimately succeed, it needs catalysts. There have been many similar projects in the past - every one of them tried to be made 'compulsory' one way or another - and they all pretty much failed in the popular realm.
If you look at the wikipedia entry (german)
https://de.wikipedia.org/wiki/Gendersternchen you can also see, that adoption has been sparse so far.
Those things come an go. Its largely not as you represented it, that it would get worse, and worse - as time goes on.
At least not in practice.
