Google has been slowly poisoning AOSP for years, ensuring the antidote is to include their services. AOSP now is mostly just a shell. This was reinforced just a few days ago when I downloaded and setup Android Studio for the first time in years: the default AVD with their APIs integrated works really well out of the box, but when I tried creating a couple AVDs without them, they wouldn't even boot (AVDs in my old setup still work fine, but that's on my previous computer).
