Retest for regression was successful, TF framework handles empty timeouts block out of the box, no inconsistencies.

Subscription was CICD application.

Here is the sample configuration used to validate the setup:

provider.tf

terraform {
  required_providers {
    btp = {
      source  = "SAP/btp"
      version = "~>1.4.0"
    }
  }
}

# Configure the BTP Provider
provider "btp" {
  globalaccount  = var.globalaccount
}

main.tf

locals {
  project_subaccount_domain = lower("${var.subaccount_name}")
  project_subaccount_cf_org = substr(replace("${local.project_subaccount_domain}${var.org}", "-", ""), 0, 32)
}

resource "btp_subaccount" "sa_devops" {
  name      = var.subaccount_name
  subdomain = local.project_subaccount_domain
  region    = lower(var.region)
  labels    = var.subaccount_labels
  usage     = var.subaccount_usage
}

resource "btp_subaccount_entitlement" "cicd_app" {
  subaccount_id = resource.btp_subaccount.sa_devops.id
  service_name  = "cicd-app"
  plan_name     = var.cicd_service_plan
}

resource "btp_subaccount_subscription" "cicd_app" {
  subaccount_id = resource.btp_subaccount.sa_devops.id
  app_name      = "cicd-app"
  plan_name     = var.cicd_service_plan
  depends_on    = [btp_subaccount_entitlement.cicd_app]
}

variables.tf

variable "globalaccount" {
  type        = string
  description = "The globalaccount subdomain where the sub account shall be created."
  default     = "PUT YOUR GLOBAL ACCOUNT SUBDOMAIN HERE"
}

  default     = "devopsdemo"

}

variable "org" {

  description = "Your SAP BTP org e.g. department"
  default     = "IT"
}

variable "subaccount_usage" {

  default     = "NOT_USED_FOR_PRODUCTION"
  validation {

    error_message = "Invalid value for the subaccount usage. Only 'NOT_USED_FOR_PRODUCTION' and 'USED_FOR_PRODUCTION' are allowed."
  }
}

variable "cicd_service_plan" {
  type        = string
  description = "The plan for Continous Integration & Delivery subscription"
  default     = "default"
  validation {
    condition     = contains(["free", "default"], var.cicd_service_plan)
    error_message = "Invalid value for Continous Integration & Delivery. Only 'free' and 'default' are allowed."
  }
}

variable "subaccount_labels" {
  type        = map(set(string))
  description = "Labels for subaccount"
  default     = { CostCenter = ["123456789"] }
}

@vipinvkmenon @CHERIANS: when doing the review, please also validate the regression e.g. via the sample configuration provided above.

Tested with the provided configuration. Works as expected. Empty timeout blocks are also handled properly as mentioned by @lechnerc77
