这些 EK_EXPORT_* 便捷宏会把 fn 传入 EK_EXPORT，而 EK_EXPORT 会在符号名里做 __init_##fn##prio 的 token-paste；因此 fn 实际上必须是“函数名标识符”，不能是任意函数指针表达式（例如 &fn、强转、括号包裹的表达式等），否则会触发预处理/编译错误。建议在这些宏附近补充注释/文档，明确 fn 的用法约束。

EK_EXPORT_HARDWARE/COMPONENTS/APP/USER 的优先级值整体 +1（硬件从 0 变成 1 等），会改变启用 EK_EXPORT 时的初始化调用顺序；如果已有代码依赖旧的宏优先级，这会造成行为变化。建议至少在头文件中明确说明该优先级映射已变更，或提供兼容旧映射的别名宏以避免静默破坏。
