Right, but still my CarbonOS idea ('degraded' GrapheneOS) is better than /e/, Lineage, Calyx, and stock. By 'degraded' I mean the minimal changes to current GrapheneOS needed to get it working on a given GrapheneOS-unsupported device.
Most people expect to have decent encryption without a strong passphrase, at least 5 years of security updates and a lot more. Fairphone says they provide updates far longer than they do for many components, and those come with substantial delays. Fairphone 5 and earlier have end-of-life kernels without security support. That's a very bad situation and is widely ignored. The more recent devices are headed to the same situation for the Linux kernel and other components.
