Hello! Please have a look on https://www.osm.org/way/294776561. What is the mean of the tag man_made:2023? 

A small note: A key with a year number means that it only existed in that year. 
If there is a year number with a minus sign in front of it, the key only existed until that year. 
A year number with a minus sign after it means that the key has existed since that year.
