  * ### Maintainer note
  *
- * This function works well on the JS thread performance-wise, since the JIT can
- * inline it. However, on other threads it will not get optimized and we will
- * get a function call overhead. We want to change it in the future, but it's
- * not feasible at the moment.
+ * This function is supposed to be used only in the React Runtime. It always
+ * returns `false` in Worklet Runtimes.
