hdf5+zstd is not a thing (or at least not a thing that's interoperable or usable 5y from now). I just wish there was a good off-the-shelf solution, this stuff is not difficult.
yeah, just pointing out that there's nothing inherently wrong with hdf5 and that the gains you speak of are likely from just from the use of modern compression standards.
maybe there's room for a simplified standard... or maybe just the addition of better compression to hdf5. (although they move slow for very good reason)
