as LineageOS 15.1 is just around the corner and I had a few spare CPU cycles, here's the current build which I did as a 'code of honor'-member. Just flash with TWRP as usual, add gapps (stock are too big) and optionally root.
Watch out as the whole rom might still lack a few features.

Credits to anyone who worked on them including intel for their buggy CPUs enabling me to build.
Camera does not work yet, but as far as I can see there are a few things in review to be submitted. Stay tuned as I will be building the rom again as soon as those changes are merged. In the meanwhile I may do some tinkering on my local build.
I doubt that it's SELinux. Looking at the logcat the problem root seems to be the HAL and that we should use the CAF stack. Besides that some clocks seem to be out of sync (mainly front camera). If it would be SELinux, logcat/dmesg would show.
