The implications for the ROM community would be amazing. Reading this, the implication is that the LineageOS project can make a single build that would work on all Android devices that have 1) Treble support and 2) an unlocked bootloader. In the text it is in fact implied that Google themselves make such a 'single' AOSP build/system partition that the device needs to be able to run to pass Google Play certification. It would no longer mean device specific builds and hoping your device is supported. No longer would it mean that you would have to tactically buy popularish Snapdragon devices to have a chance of some aftermarket support after the vendor inevitably leaves you. You would be able to run Lineage on (Exynos-based) Samsung and Huawei phones, which is either impossible or too much trouble to worth the effort at the moment. Hell, in theory alternate non Android-based, OSes like PostmarketOS [1] could write their OS to be compatible with the Android HAL and work with that. Stuff like this would have likely made Canonical's life in running Ubuntu on Android devices much easier too. Vendors could make a system partition with their latest skin version and distribute it to all their devices, instead of only their flagship ones, meaning feature updates can be deployed in a much broader way than is done now. Driver updates will likely still be an issue, but security fixes that pertain to the Android base can still be deployed. I really, really hope the implications here turn out to be true, and vendors don't find a way to fuck this up. [1]: http://postmarketos.org/ http://postmarketos.org/
