Okay, but having a stable interface doesn't fix vendors shipping bad code, it just decouples it so you can run terrible drivers on a less-terrible kernel. Better yet, Fuchsia removes any obligation for vendors to share code (by both separating drivers from the OS and having the OS itself be permissively licensed), so third parties can't even start from vendor code and try to improve things.

Just like Project Treble,

Binderized HALs => HALs expressed in HAL interface definition language (HIDL) or Android interface definition language (AIDL). These HALs replace both conventional and legacy HALs used in earlier versions of Android. In a Binderized HAL, the Android framework and HALs communicate with each other using binder inter-process communication (IPC) calls. All devices launching with Android 8.0 or later must support binderized HALs only.

These are two distinct problems. Rather, one is an improvement and another is a problem. The terrible drivers can then be isolated, pinpointed if you want, and the OS can move forward - if you don't use the AMD GPU or the HP printer no need to have it bloating your kernel, so I take this as the improvement (I was always fond of microkernels, so I'm advocating here). On the second problem, I fail seeing how the blame for vendors failing to update their drivers could fall on the OS. With this approach the failing is just much more evident, not any less damaging.
