I have a drive in my pool that has had SMART errors in the past.
I can live with this considering the data stored in the pool and the nature of the errors.
But it leads to a big warning on the dashboard with the rather vague text "One or more of your drives is being reported as unhealthy." I can remove it by disabling SMART for the disk in TrueNAS. I would rather be able to somehow acknowledge the errors that have been experienced, so I can get rid of the warning, but be warned again if a new error occurs, or if another drive experiences an error.
The current behaviour risks masking errors that the user should handle immediately.
