Exactly this is why it probably won't make it into the game.
Killrob once made a video for Automation with a lot of frequent asked questions. In that video, he didn't state this question specifically, but he explained to other questions that when its not mass-used, it won't probably make it into the game.
Let me give you one "small" example;
Diesel engines. How big of a chance would you guess they have to make it ingame at this point? The majority will probably say (just like me before the video) over 80%.
Killrob took the marketshare statistics on Diesels and did some calculations with it on the go in the video. It proves they had a total marketshare over the years of under 10%. (Can't recall the actual number)
Thats far too low to even consider at this point. But because of the bigger marketshare it has created over the last 20-30 years, Diesels will definetly come with DLC. (If the game proves to be succesful!)
As for the things you spoke about, those will probably be modded in by the community at some point, and when good enough, adapted by the developers probably.
