Porting to other systems is not easy. A programmar has to test a lot, and this update isn't even a stable one. It's performance is kinda janky and it has the most bugs I've seen in one of FNF's major updates. And you expect them to functionally port it to Linux? A system the devs don't even use? You have to be patient, and you have to understand stuff like this is never as easy as it seems.
