+> Stability: 1 - Experimental. Please migrate away from this API, if you can.
+> We do not recommend using the [`createHook`][], [`AsyncHook`][], and
+> [`executionAsyncResource`][] APIs as they have usability issues, safety risks,
+> and performance implications. Async context tracking use cases are better
+> served by the stable [`AsyncLocalStorage`][] API. If you have a use case for
+> `createHook`, `AsyncHook`, or `executionAsyncResource` beyond the context
+> tracking need solved by [`AsyncLocalStorage`][] or diagnostics data currently
+> provided by [Diagnostics Channel][], please open an issue at
+> <https://github.com/nodejs/node/issues> describing your use case so we can
+> create a more purpose-focused API.
