For intuitive use having everything related to data linking under the “object” menu would make more sense somehow. But having it under relations is faster for repeated use I believe, because once I navigated there, I can keep linking materials, modifiers, etc for multiple object groups without having to dig through menus again. The best alternative for intuitive use and speed would probably be to bring back the shortcut and the popup menu from blender, that can also be called from the “object” text menu.
