How to listen "initial" onPatches on RootStore?

[PEZO19]

Assume RootStore's onInit starts an action.

onPatches(new RootStore({}), ()=>{})

Even instantiating here, we miss patches. Is there an official way to do that, am I missing something?

My ideas:

1. subscribing in onInit itself, however this might be limited as the (lexical) scope/context is limited.

   onInit(){
   const disposeRootStoreOnInitPatches = onPatches(this, ()=>{
      // we can get rid of it and fallback to the original onPatches as shown above
      disposeRootStoreOnInitPatches()
   }
   }

2. We could introduce a "RootStoreParent" / "RootRootStore". (But maybe wrong too as RootStores onInit is called before attach/listening?)

   const rootStoreParent = new RootStoreParent({})
   onPatches(rootStoreParent, ()=>{/*...*/})
   // at this point, we have a listener above RootStore
   rootStoreParent.instantiateAndAttachRootStore()

3. Workaround: restrict onInit somehow, so it won't cause any patches to miss?
