Description
There are currently instances when we want to use arrays of zeros in which size information is retained - this is not something supported by the Zero differential, but which is supported by FillArrays.jl's Zeros type. I would be nice to use this here, but are there perhaps issues with it not defining setindex?

Research direction
Start by reviewing the existing Zero differential and the related discussion in issue #15, then compare its behavior with FillArrays.jl's Zeros type. Check whether the lack of setindex support affects the proposed integration; done means establishing a clear implementation approach and validating the relevant array and differentiation behavior.
