Hi @Abram Ziegelaar and thank you for this idea. 

As you probably know, adding Data Modeling support to our PowerBI connector is in progress at the moment, but we’re unlikely to pivot to a GraphQL driven PowerBI connector at this stage. 

However, this is an interesting concept that we will assess! As the Product Manager for Data Modeling, I will process this idea and update you as we have new information.

This functionality is also requested by other users. Ref:

Cognite PowerBI: Need Direct Query and Live Streaming Capability

The request is to have Cognite assess the suggested third party connectors & advise if they work correctly with CDF. If so, it would potentially avoid the need for Cognite to develop such a connector.
