Opening (and closing) a ZipStore when given a path ending in ".zip" would largely solve it I believe -- in fact, I tried just providing a path with ".zip" to to_zarr before, hoping it would work. (And indeed, I did so because the many small files are troublesome.)

open_zarr already automatically accepts path ".zip", so it would be nicely symmetric as well. However, this behavior exists within Zarr, not Xarray.

https://github.com/zarr-developers/zarr-python/blob/473576f3b17ac4a460dfccbcc4860606cd8123ed/zarr/creation.py#L130-142

I'd be happy to have a try at a PR in principle.

Maybe it could be as simple as adding a with? ```python

if isinstance(store, (str, pathlib.Path)): if str(store).endswith('.zip'): with zarr.ZipStore(store) as zstore:

etc

```

In the xarray.backends.api.to_zarr() function.
