I wouldn't call all of the errors meaningless. This error in particular is good for those of who may have 'fat-fingered' a date, or may even have conflicting sources and are not sure in which direction to go for a specific date.
While I am quite aware of the errors and lack of unsourced profiles in FAG, the headstones, cemetery locations, and other features on FAG can be of use to users here on WikiTree.
With that said, I may have misinterpreted your statement of "repeatedly" telling the system that your sources are correct and not the information on the FAG record. In my answer, my process is only done once per profile and it clears the error - I will never see it again unless something is updated, a new or changed FAG link is added to the profile, etc.
Also, if you are not handling those suggestions, and ignoring them like they do not exist, could they then be caught up in a sourcing or data doctors sprint since they technically still exist as an error? If they were, your profiles are now going to be reviewed and possibly edited by other members or having to be cleared by other users.
I myself am tired of seeing the DBE_503 error, "Probably wrong gender (male)", and the DBE_511 error, "Unique Names (spelling)" - but I handle those errors as they come up in order to lessen the burden on myself and others:
- So I don't have to see the error again in my suggestions report; and
- So other users are not wasting their time trying to edit the profiles I am working on or trying to clear my errors for me.
