Please do what you can to make EVERY connection type in Fabric support Service Principal authentication, AND make it so that the Secret (Service Principal Key) can be stored in an Azure Key Vault.

For the love of god. Yes please. It seems absurd that this hasnt been a priority until now. Our Fabric Architecture breaks every once in a while for needless Entra related Identity issues. Service principals everywhere. Secrets accessible for service principals. I just set up everything assuming this would function and am beyond disappointed that our azure key vault sits uselessly connected to fabric, because it cant talk with service principal connections somehow.
