I would assume Unity has something in the works internally, but it looks like someone is creating a Nanite/Lumen equivalent for Unity here:

As for Metahumans, Unity has started on an equivalent of that too:

Character Creator is also looking like they're stepping up their game to match Metahumans:

That said, I'd love to see these things come to Godot specifically, including performance on the level of Unity ECS/DOTS.
