AOSP isn't dead, but Google just landed a huge blow to custom ROM developers

TL;DR

• Google has made it harder to build custom Android ROMs for Pixel phones by omitting their device trees and driver binaries from the latest AOSP release.

• The company says this is because it’s shifting its AOSP reference target from Pixel hardware to a virtual device called “Cuttlefish” to be more neutral.

• While Google insists AOSP isn’t going away, developers must now reverse-engineer changes, making the process for supporting Pixel devices more difficult.
