I can get the source of the kernel, including all drivers, running on my android phone with a few clicks and build a custom ROM.

No, most drivers are closed source and you can just extract binary blobs for them. They run as daemons that communicate through the binder ipc - Android basically turned the Linux kernel into a microkernel.
Indeed, since Android 8 all drivers are in userspace and use Android IPC to talk to the Linux kernel.
Traditional Linux drivers are considered legacy in Android.
Yep, my Pixel 5 with stock OS and Pixel 6 with Graphene are hacked via WiFi blobs, which are not updated and cannot be patched.
