Yes I know, and I want to try DivestOS one time. But they do incomplete patches.
They cannot update the kernel themselves or even worse the firmware. The kernel needs to be built and patched for the specific hardware, GrapheneOS relies completely on Google here. And the firmware needs to be signed by the vendors, so no chance either.
And especially baseband, cellular stuff has extremely many vulnerabilities in the code.
I think 3a is already too old. I think 4a is a better minimum, but this is still insecure of course.
