Well I don't know, that's mostly the goal of that issue to investigate that, but yes that will probably involve looking at how ORM do batching and how we could reuse the code or the logic and bring them back to OgmLoader or some hierarchy thereof.
My guts tell me is that reusing the ORM infra or logic won't be enough for the case where we receive the list of ids loading a collection and we want to load these n ids in one shot. For once, we don't really receive all of the ids in one place in the code, it's more one at a time.

The morale of the story is that it needs investigating
