AAS should be able to connect to the Databricks ODBC server, just like it can connect to HDInsight and just like PowerBI can connect to the Databricks ODBC server.

Yes - Databricks is seeing rapid adoption among organizations - AAS needs this connector.

Completely agree... AAS is also a very common data consumption source that, in my opinion, Databricks should be able to connect.
