/e/ are currently making and testing Android R builds for devices that are officially supported by LOS, presumably basing their work on tha changes LOS have made to upgrade for Q to R.
What is the plan for devices which are officially supported by /e/ but not officially supported by LOS?
For example, I maintain the official /e/ ROM for Sony Xperia XZ1 Compact, which is currently based on an unofficial LOS 17.1 ROM. The maker of that ROM now has an unofficial LOS 18 build, which seems to be working well. What do I need to do to move the /e/ ROM from Q to R?
