Use managed identity instead of AzureWebJobsStorage to connect a function app to a storage account

I use exactly that for a Function App I have. I replaced the setting AzureWebJobsStorage by AzureWebJobsStorage__accountname and removed the WEBSITE_CONTENTAZUREFILECONNECTIONSTRING which also contains the connection string to the storage account. However, I have a warning message because the WEBSITE_CONTENTAZUREFILECONNECTIONSTRING setting is needed for Azure Files mounting which is used by Azure Functions at the platform layer. However, having this implies using the secret connection string for the storage, and the whole point of using https://docs.microsoft.com/en-us/azure/azure-functions/functions-identity-based-connections-tutorial#use-managed-identity-for-azurewebjobsstorage-preview was to avoid using a secret for Azure Storage. This https://github.com/Azure/azure-functions-host/issues/8135#issuecomment-1040879695 says that Azure Files does not support using AAD identities for SMB mounting. So my question is:  when is it planned to be supported? Is it already the case and I'm missing something?
