serialization 在 Node.js < 12.16 时可以传递任何值，不会异常。在 >= 12.16 时非 json advanced 值会抛异常。

另，是否需要在 debug 模式时默认设置为 advanced 值？
或者当 >= 12.16.0 时全部默认 'advanced'？

+| require         | `Array\|String` | will inject into worker/agent process                                         |
+| pidFile         | `String`        | will save master pid to this file                                             |
+| [serialization] | `json|advanced` | default: 'json'. 'advanced' requires Node.js >= 10.16.0                       |



这里是 12.16.0 吧？

另，是否需要在 debug 模式时默认设置为 advanced 值？
或者当 >= 12.16.0 时全部默认 'advanced'？

我看了下下面的相关讨论：nodejs/node#30162 (comment), 看起来 advanced 并不是所有场景下都是最优解，所以这里确实应该 follow 上游的设置，默认为 'json'，但是在框架里在适当的版本暴露可配置选项。

我也是如此考虑：随着版本更新性能提升及可靠性得到进一步验证，可能在未来某个版本默认改为 advanced。
所以跟随 node.js 默认设置（json），代码里面不做默认值设置，让有需要的用户自行决定传入参数控制。

hyj1991 · 2020-02-14T01:42:40Z

    if (this.options.isDebug) opt.execArgv = process.execArgv.concat([ `--${semver.gte(process.version, '8.0.0') ? 'inspect' : 'debug'}-port=${debugPort}` ]);

+    /* istanbul ignore next */
+    if (semver.gte(process.version, '12.16.0')) {


这里的判断有一个问题，'v13.0.0' 也是 >= 12.16.0，但是这个版本 patch 了此功能么

对于 12 版本是 >= 12.16.0，对于 13 版本是 >= 13.2.0。
代码已更新判断条件。

感谢您关于 v12.16.0 更新的支持更多 IPC 序列/反序列化的配置参数 PR，以上是我的一些对于 PR 代码的修改建议，期望可以一起针对修改/不修改的合理性进行讨论 :)

如果这个未来还会变化的话，那目前能否先通过 NODE_OPTIONS ENV 的方式来使用就好了？

>= v12.16.0 < v13.0.0, or >= v13.2.0

NODE_OPTIONS ENV

这个变量设置是否影响 forkAgentWorker() 对 agent 进程的派生。

影响的，fork 默认是继承 env 的。可以试验下

就是说不修改代码，通过设置 ENV 也能起效果。那我关闭这个 PR 了哟？

我理解是这样的，你实验下看看

所以这个 PR 还有下文不。。。
