Why do government libraries use react context for dependency injection?

I looked at the source code of two well-known government control systems for React and found out that both of them use the React context as a dependency container ( MobxProvider

, ReduxProvider

). On the other hand, I find it good practice to try not to use React related constructors for libraries (especially context), and I think it is possible to create a separate module for the dependency container. Here is a naive implementation of my thoughts:

let container = {};

const register = (obj) => {
  Object.assign(container, obj);
}

const getAll = () => container;

export { getAll, register };

      

        
        
        
      

    

Am I missing something? Are there any edge cases that cannot be maintained just by using a module? Why are they using context as their dependency container in React?
