Fsspec allows URLs like "az://container@account.blob.core.windows.net" (https://github.com/fsspec/adlfs/blob/38c393299d61895689b96cae5ff21895724e3fe2/adlfs/spec.py#L404),
Object store now supports these urls only if the endpoint is ".dfs.core.windows.net", even if it has support for ".blob.core.windows.net" in the "https://" scheme.
I would like to add support for it in the "az://" scheme, because that seems to me like the best way to have both fsspec and object_store compatible URLs.

Describe the solution you'd like
Allow URLs like "az://container@account.blob.core.windows.net"

Describe alternatives you've considered
Convert all URLs with ".blob.core.windows.net" to ".dfs.blob.core.windows.net" before passing them to object_store, but this is unnecessarily inconvenient.

Additional context
A few days ago a MR in object_store added support for "az://container@account.dfs.core.windows.net" URLs: (#285).
