Changing a building block input name forces replacement

[JohannesRudolph]

I have a meshstack_buildingblock resource and did change an input that I misnamed from region to region_name.
Upon doing so the terraform provider wants to now replace the BB instead of performing an update operation on it.

OpenTofu will perform the following actions:

  # meshstack_buildingblock.enable_eu_south_2_region must be replaced
-/+ resource "meshstack_buildingblock" "enable_eu_south_2_region" {
      ~ metadata    = {
          ~ created_on             = "2025-06-12T13:52:12.769832Z" -> (known after apply)
          ~ force_purge            = false -> (known after apply)
          + marked_for_deletion_by = (known after apply)
          + marked_for_deletion_on = (known after apply)
          ~ uuid                   = "f72002f6-bead-4b42-93a0-ef2a635d6667" -> (known after apply)
            # (3 unchanged attributes hidden)
        }
      ~ spec        = {
          ~ combined_inputs        = {
             # some omitted...               
              - "enabled" = {
                  - value_bool = true -> null
                },
              - "region_name" = {},
            } -> (known after apply)
          ~ inputs                 = {
              - "region" = { # forces replacement
                  - value_string = "eu-south-2" -> null
                },
              + "region_name" = { # forces replacement
                  + value_string = "eu-south-2"
                },
            }
