I think that this developments on the linking and graphing features in obsidian would power up the connections and navigations trough concepts a lot. I’m not sure I follow completely de concepts you brought here, but seems already very relevant.
One feature associated to the graphical display I think should potencialize the usage are the local connections graph per page [like the Roams sidebar, capturing the concepts directly linked in the specific page you have open] and also some features for sorting the information in different ways, just like the Roam Graph view where you can sort that like a tree-view of the concepts connections.
Hope they get to develop these features in the near future, or even the community plugins.
