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.
