Allow Paas Services to connect to firewall protected storage as "Trusted Services"
Currently only very few Azure PaaS services can connect to a firewall protected Storage Account, but practically all data integration tools (Data Factory, Data Lake Analytics, Databricks, Azure DW Polybase, Logic Apps, Azure Functions etc). are not considered among these "Trusted Services".
More and more of our Azure customers are complaining about this missing feature as alternative methods are clunky or not available, depending on the scenario.
There are multiple ideas regarding the same issue, each for specific service. But I see the problem as more foundational, it is not a question of which PaaS services should be included, more like which I choose to include/exclude in the firewall.

Storage Accounts do not support Microsoft.Web yet as Trusted Microsoft services. Using a firewall enabled storage account as the destination for Web App backups is not supported. If a backup is configured, I get failed backups.
