Hey Graham, thx for you reply.
My colleague is currently trying to implement Microsoft Fabric using Pulumi, but has been relying on the Terraform provider. Unfortunately, the Terraform provider for Fabric is not yet complete, which limits our ability to fully automate all required resources.
We think about implementing our own provider. The huge problem is, fabric is still experimental at MS and TF.
