More info: - Memory usage can already be reduced for many applications with either `deriv_mode="blocked"` or `jac_chunk_size=1` and `deriv_mode="batched"` on the outer `ObjectiveFunction` - with maximal memory reduction with `deriv_mode="blocked"`...

This was not really resolved by #1166. We came up with a hack for the two cases that exist in the current code. Is that solution our plan going forward...

We think the issue is caused by returning the metadata from the root solve, which can include non-differentiable data types
