Project Treble has been one of the best things to happen to Android in quite some time. Treble separates the vendor implementation from the main Android framework and system, allowing OEMs to update devices quicker and with lesser dependence on driver updates from silicon manufacturers. This should allow for quicker updates as well as for, hopefully, longer update cycles. Project Treble also enables the installation and use of what is called a Generic System Image— a single system image that can work across a really wide variety of Treble-compatible Android devices. Project Treble and GSI's have revitalized custom ROM development, and the effort is being led by developers like XDA Recognized Developer phhusson.
Phhusson's custom AOSP Project Treble GSI has now been updated with the latest March 2019 security patches as well as a whole host of other fixes. The goal of the GSI/ROM is to provide maximum hardware compatibility within the GSI, allowing porters to have a much easier time using this on newer devices. The base can then be used to add on software features and other device specific fixes.
