Cannot create a vdc with system default Sizing Policy (used as default compute policy) and VM Placement Policies

Terraform Configuration Files

I can create a vdc not specifying vm policies:

resource "vcd_org_vdc" "vdc" {
  . . .
  default_compute_policy_id = null
  vm_placement_policy_ids   = []
  vm_sizing_policy_ids      = []
  vm_vgpu_policy_ids        = []
  . . .
}

vcd creates a vdc with a system default sizing policy (empty) used as:

default_compute_policy_id
default_vm_sizing_policy_id (deprecated)

Expected Behavior

Using the UI it is possible adding VM Placement Policies leaving the default_compute_policy_id and default_vm_sizing_policy_id (deprecated) untouched.
Using terraform, I cannot create a vdc with system default Sizing Policy (used as default compute policy) and VM Placement Policies, because I cannot specify the id of the system default Sizing Policy (known after apply) and cannot be null.
I think it should be possible to set system default Sizing Policy as default_compute_policy_id even when a placement policy is added to the vdc.

As a workaround I created a dummy/empty VM Sizing Policy on cloud director, I assign it to the vdc and set it as default compute policy, so I can set placement policies.

I've added a comment on the closed issue #1037 but I think it's better to open a new issue.

thanks
