True, but the general usefulness of noting prior submissions is that the principle discussion is / has occured there.

If mods have elected to promote another submission, the comment serves little or no useful purpose.

I'll usually delete my own "dupe" notice comment if I realise that's the case. I commented above to provide clarity to anyone confused by your initial comment.

(I do appreciate that you note dupes with formidable frequency and accuracy. All of us stumble occasionally.)
