xarray/dask read methods
On reviewing the most common user-facing API in the wild, @grlee77 pointed to zarr.open as well as the equivalent methods from xarray and dask. With issues like https://github.com/dask/dask/issues/7673 in mind, we may want to have regular tests of these methods.
That was based on manual inspection of a handful of packages that list Zarr as a dependency, but GitHub-wide searches also indicate these are all widely used:
dask.array's from_zarr https://github.com/search?q=%22from_zarr%22&type=code 459 source code matches found
