在 WWDC 2024 的 "What’s new in StoreKit and In-App Purchase" 会议中，提到 StoreKit 2 提供了许多改进，包括自动执行加密验证和使用现代语言特性来处理任务，如获取产品元数据、购买和检索客户交易历史。关于每次冷启动执行一次恢复购买（restore）的风险，具体的风险并没有在提供的上下文中详细说明。
然而，通常情况下，频繁地执行恢复购买操作可能会导致不必要的服务器请求，从而影响应用的性能和用户体验。此外，过于频繁地调用恢复购买功能可能会导致用户界面上的延迟或其他问题。
为了更好地理解和处理恢复购买的操作，建议查看 StoreKit 2 的文档和相关的 WWDC 会议内容，特别是关于 StoreKit 2 的更新部分。你可以在 What’s new in StoreKit and In-App Purchase (21:06) 中找到相关信息。
