@triskelion @comex It uses the same kernel.org LTS branches that are officially supported for each device, but we switch to using the latest GKI LTS revision from Greg KH which are based on the kernel.org LTS releases.

We could use the current 6.1 LTS everywhere in theory but we don't want to deviate so far from what's heavily tested and officially supported, so we stick to what's officially used which will get officially migrated to newer LTS branches now that devices have 7 years of support.
