In adlfs (fsspec), there are two valid conventions for specifying a canonical path to Azure Data Lake Gen2 storage, including the account name:

az://container@account.dfs.core.windows.net/path-part/file
abfs://container@account.dfs.core.windows.net/path-part/file

While object_store supports both the az and abfs protocols, it does not support specifying the account in the URL for the az protocol.
However, it does support this for the abfs protocol.

Describe the solution you'd like
I would like to be able to use the following URL convention with object_store, which improves compatibility with adlfs:

az://container@account.dfs.core.windows.net/path-part/file

Describe alternatives you've considered
The workaround is to remember that I need to use the abfs protocol in object_store based tools such as polars.
However, it would be nice to be able to use the az protocol for everything.
