Ironically, I'm not expecting a single thing, hence my pessimistic post where I assumed that Early Acces is just a not-so-elaborate ploy to already get some of our hard-earned moneys. Sounds a bit bitter when I type it like that, but in conjunction to you, rightfully suggesting, to not getting my hopes up, this is sadly the most reasonable outcome. I guess, I`ll have to wait for hoping that there's a modding community out there that they themselves had similar suggestions and the skills to implement it.
That is my point. You seem to much focused on only your feedback and then assume it is just a cash grab. They have shown in the past that they listen to feedback (not to everything, they are still only doing what they want to do). But the catch is: they will probably listen to things more that more people are interested in. Things in your list that you think are not immersive many others may have no problem with. So you can assume that they probably won't check every little point off of your list. But things like hiding helmets I would take a bet, that they will come in a future patch/1.0 as a LOT of people have brought that up and they had it in their past games too.
I really don't think its a cash grab, but it would be wrong to assume that they will evaluate EVERY little feedback, even if it is objectively reasonable.
