That only works for the userland, mitigating security issues by replacing the main stock OS with Lineage. Aren't most LOS roms based on ancient kernels (albeit mostly patched-up with security updates), that use ancient modules, with opaque BLOBS/Firmwares, that only sometimes get updated, if ever? You could run "HighSecurityOS WhatEv" on your phone, as long as e.g. the Wireless-Interface runs something entirely independent of you with DMA rights, and probably faulty firmware, can you really trust your device? Or have I missed recent advancements in this problem space? PostMarketOS aims to mainline more devices/phones, so maybe, even if your final OS of choice is Lineage (or derivative), I would check their HWCDB before checking, if Lineage works on a phone.
