Description
At the moment these custom operations aren't yet part of the public API, but they should make it possible to replace unvmap_* and nondifferentiable_output, which are currently implemented as custom primitives.

Research direction
Start by locating the implementations and usages of unvmap_* and nondifferentiable_output, then compare their behavior with JAX's custom_batching.custom_vmap and custom_transpose.custom_transpose. Confirm that the replacement APIs are public and still available before proceeding. Done means the custom primitives are replaced without changing the operations' behavior.
