This. The devs don't have a say in the tech stack. The decsion is usually outsourced to the lowest bidder. Other than Tesla and Rivian, I can't think of any OEMs that I've dealt with who have full control over control over their display. Almost everyone outsources it to the Koreans who have a lock on that market – i.e. OEMs send in their designs but it's actually implemented by LG, Samsung etc. From what I've seen, any changes or new additions to any on-screen components has a 2 year lead-time unless (not a typo) it's safety critical or catastrophic in some other way.
