Thank you for these information, and also for your more detailed view of the object changes.

By the way, a little bit OT. I assume one of the main use case of MAPS.ME is routing and navigation. I found interesting behavior if there are barrier=bollard on highway=*. So I also found ongoing open issue at github [1], could you check this, what is the status of finding a solution?
