I think you hit it on the nail with "who do you trust"... I just wanted to bring it to the attention of the community because I was not sure how folks are monitoring the health of their drivers. I for one was relying on smart tests but once it was removed from the GUI it made me look for alternatives. The reason it was removed from the GUI according to truenas is because the majority of the pools being used are not machinal drives and the smart tests only apply to mechanical drives. I think moving forward I am going to use both, cron jobs for smart tests since mine are still mechanical drives and these tests are very much still relevant and also see what scrutiny has to say. having said that, I just would have loved single source of truth and I do think that bouncing back and forth between the 2 is not efficient and it needs to be clearly stated which is the gold standard (single source of truth).
