Hi, welcome to OSM.

Please do not delete/replace data in order to express the same feature. I was going to contact someone regarding this way https://www.openstreetmap.org/way/94798023 which was crossing a wall and noticed I couldn't anymore. Restored it. Also when a feature does not exist anymore, often we tend to life-cycle the data with a prefix like abandoned:key=value or razed:key=value or demolished:key=value to inform other contributors in case they are not aware of the situation and use an outdated source, just like Jakka who is from Belgium contacted you 3 months ago to get the information for the residential road. See what I did here https://www.openstreetmap.org/way/1285956842

For the separated building of the drink shop at Cactus 72851565, I think the original contributor was right to separate it. Costumers cannot access it from the inside, they need to get out and enter the front main entrance. I restored the building and reshaped the other.

You can get informations and good practices here https://wiki.openstreetmap.org

Enjoy the mapping!
