The question arose at the EOSS kickoff meeting whether it would be possible to make a suggestion for the numpy io documentation (https://numpy.org/devdocs/reference/routines.io.html) for use of zarr as a (eventually the preferred?) mechanism for persisting numpy arrays. Text is needed for the top under "Input and Output" at the top as well a block dedicated to Zarr down below. Minimally a PR against https://github.com/numpy/numpy/blob/master/doc/source/reference/routines.io.rst is needed, but there may be other locations that need cross-referencing.
