Anything out of this thread is considered as off topic and unrelated, there are modules to bypass safety net if you aren't aware abt itLol some people have been running Lineage OS 17 for months now.
@AndyYan has been posting updates for treble devices:

In any case, I did not have safety net issues on some of the older versions so I'm still experimenting.
