The N5Store works great for storing local files. What are the technical challenges in moving to support something like GCS for storage? Other pieces of the zarr library seamlessly work if I move to gs:// prefixes (with the right packages installed), but N5Store ends up writing to the local filesystem when using that prefix.

Is it a matter of going through n5.py and storage.py and changing uses of the os library to uses of fsspec? Or are there operations that fundamentally won't work on cloud objects?
