When ESRI staff merge ideas by converting the duplicate idea to a comment:
It would help if the comment could indicate that it was inserted by the system/ESRI — and was formerly an idea.
Reason:
Comments that were converted from ideas often appear to come out of nowhere. As far as I can tell, there's no way to tell that they were originally ideas. Example: https://community.esri.com/t5/arcgis-pro-ideas/calculating-the-x-and-y-coordinate-automatically/idc-... That idea—>comment doesn't have any context. So the person who had commented previously was confused, since they’d already addressed the issue in a previous comment.
If some background info were added as a auto-generated header, explaining where the comment came from, then that would avoid confusion.
"This comment was originally a separate idea; merged."
