That's defnitely a big benefit. I used LineageOS (whatever it was called then) to extend the life of my Galaxy S, but at that time not having a working phone for awhile was a lot less disruptive to life and work, so I didn't attempt this time. But once I'm 100% migrated to my new Pixel 7, I'll certainly put an alternative ROM on the Pixel 2 to extend its non-phone life!
It used to be called CyanogenMod and it was easily hacked by the UK authority's.
