At least for the GPU information it seems relevant. What value are acceleration device cache topologies outside of the subsytsem that uses them?

I don't disagree, but I'm not sure where the best place for these should be. Probably a lack of knowledge of where this should actually live and indifference from the maintainers of those areas since this use case doesn't match existing ones.
