Interesting project. Thanks for sharing! Any reason why at least some of those patches couldn't be upstreamed to LOS?

Most things simply aren't in their scope.

I do send occasional patches to Lineage if they are in-scope and am in contact with some of them reasonably frequently.

The big blocker is that their Gerrit instance requires a Google account to login.

Example of a recent fix I emailed them: https://review.lineageos.org/c/LineageOS/android_device_htc_...
