Unifying the two has never been an internal goal until 2024. I'm not sure why you think otherwise. Everything before that has just been rumors and maybe one off projects by very small amounts of people. Rebasing ChromeOS on the lower half of Android is real and has been publicly announced. It is not necessarily the layers you will notice through. It's about unifying things like the kernel, display stack, power management, Bluetooth stack, etc. There are effectively divergent universes between ChromeOS and android (and the desktop Linux ecosystem) despite these things not necessarily requiring unique solutions.
