Hello dear NeretvaRiver.
I would also like to note that the first link you provided concerns simple intersections 1+2 and 2+2, and not a road junction with a roundabout, and this rule is not a dogma(!) for a roundabout.
Regarding the second link, it says that the point of intersection of two lines is needed for the router to correctly determine the route options. In our case, the point you mark creates an erroneous route, since there is already a link to this point from this road to the right.
Also, I would like to notify you that I know and studied all the points you cited when I started working at OSM 12 years ago. I myself live in Azerbaijan, and due to my professional activities I know all the road regions in the country very well. It may not seem modest, but I note that 75% of the map of Azerbaijan was edited by me. That is, in terms of experience and editing practice, I seem to be doing quite well. The rules for editing in OSM themselves were created on the basis of agreements between OSM participants (every written rule begins with this phrase), and my experience shows that they are not ideal and are regularly adjusted.
Sincerely.
