Question ConvertGameObjectHierarchy being deprecated?

I recently read the following note from the part 2 of the data design course.

So, how would I replace runtime prefab conversion with editor code if I don't know which prefabs will be instantiated until runtime?

Sure, if I have a cube in a trivial example, just place a Convert to Entity component on it. But, in a hybrid situation where prefabs are referenced in scripts, this seems far less obvious.

 

I think they plan to deprecated and replace with a faster runtime API. At least that was what I told in a tech support email.

You can also convert and save a ref for entity prefabs now for later run time use.

 

This works if you have a known, relatively small set of prefabs that you'll be instantiating at runtime. But if you have a huge pool of prefabs, only a small subset of which you wish to instantiate in any given instance of your game, then it's not very practical.
