I'm asking because of this question: How do I depower Magic items that are op without ruining the immersion tagged: dnd-5e magic-items
With the help of Miniman, we commented a related question: What can I do when I accidentally gave out an overpowered item? tagged: pathfindergm-techniques magic-items treasure
I know it's not an exact duplicate but it is really really similar and the answers there could benefit the newer question.
As a potential answerer, and seeing the related question and the great answers there, I feel discouraged to write an answer that's already covered in the older question.
What is the correct etiquette in this situation?
