Review Comment:
I would consider the storage account the root dir. So that means only `1`
is the root dir. I believe this is how the fsspec implementation and the
original arrow azurefs PR did it.
I think when comparing azure to s3, the Azure storage account is analogous
to the S3 bucket and the Azure container is an extra level that S3 doesn't
have. I think `1` doesn't really reference any storage on S3.
