Back in the day I was maintainer of a CyanogenMod device. Back then you could pull the device trees and basebands and proprietary parts off the OTAs and phones directly after rooting them. Has that changed? LineageOS still exists. I haven't been in that scene for... over a decade but is Lineage freaking out to this extent? Yes, it takes effort to maintain a port and it's not as easy, but how much of GrapheneOS is actually implemented in the kernel vs post-init things (which are easy to modify).
