Hello MenKauRa. Thank you for keeping an eye on the data here!
To follow OSM Wiki guidance, all crossing highways that are on the same level must share nodes to represent the intersection (https://wiki.openstreetmap.org/wiki/Junctions#Simple_intersections), which is also called out in JOSM’s data validator for Crossing Ways (https://wiki.openstreetmap.org/wiki/JOSM/Validator#Validations).
That being said, I do understand your routing concern here and I’ve gone ahead and added turn restrictions at this intersection, to ensure turning maneuvers utilize the highway link and circular junction. Thank you for bringing this to my attention!
