If by "newbies," you mean people new to wikitree, I would strongly steer them away from db_errors project. They should be encouraged to focus on developing profiles of their own family members and getting used to how things work on wikitree, technically and style/community-wise.
If by "newbies," you mean more experienced wikitreers new to the db_errora project, project, then yes, please further explain the problem you're encountering so we can better understand the warning.
