Description

Returns current state durring planning and reading resources that require deferral. This is to correlate with new expectations of Terraform core introduced in: https://github.com/hashicorp/terraform/pull/35526

Testing this change requires running with an up-to-date build of Terraform, that includes the above mentioned PR. A build from current main would be ideal.
