> {quote}Perhaps in the future, if zero-copy and future-proof-ness is really
> what we want, we might want to add the CSF (compressed sparse fiber) format,
> a generalisation of CSR/CSC. I'm currently working on adding it to
> PyData/Sparse, and I plan to make it the preferred format (COO will still be
