For me OSM notes are mainly designed for non-members, so that everyone without an account can report issues. But OSM members can use their internal tools to communicate. In this case I would have used changeset discussions over notes.
Personally I think it takes too long and is much more hassle to create this note where other mappers now get involved to solve a problem that someone specific did who we can easily find out by checking the object history. It would be the best to clarify the situation directly with the mapper. I will definitely not wait for years, so I commented the corresponding changeset and linked it. The mapper seems to be very active so I'm looking forward for a quick solution: https://www.openstreetmap.org/changeset/113797722
