A good example of what I am saying can be seen with Apple Silicon SoCs todays - since details of some of the components in it are unavailable, system developers are being forced to reverse-engineer it to port other OSes on it. Imagine the effort to do that for 100's or 1000's of SoCs, each of which can have their own unique, custom component (with closed documentation) in it?
