This looks like the best design. Any part of the org buffer could have text properties with a list of its available actions. Such a property could be similar to 'context-menu-functions' handled by 'context-menu-map'. But since it will be a plain generic list, it could be transformed to any menu interface such as transient, context-menu, etc. To transform it to context-menu, org-mode should provide a function like 'context-menu-minor' that will create a corresponding menu that will be added as a submenu of the default context menu. Such integration with existing menus would be better than the current implementation of context menus in org-mouse-context-menu that completely replaces the context menu with its own.
