I'm implementing a custom `CoroutineDispatcher` that is an immediate behavior. I noticed that `dispatchYield` is marked with `@InternalCoroutinesApi`. Can someone confirm that this is there to prevent people from calling the method, not implementing it? Reading the documentation it seems that this is meant for custom dispatchers to implement but that you should avoid calling it manually

It should be neither used nor implemented. It used to be used in the past internally by `UnconfiedDispatcher`, but it is not used anymore, so it could disappear from API at any time.

Double-checked. It is still used internally to ensure that when you `yield()` inside a `Dispatchers.Default` it is done in a fair way. But not used for "immediate" behavior anymore. For immediate behavior you just return `false` from `isDispatchNeeded`

Ideally I would like to handle a regular dispatch and a yield dispatch differently

Right now we have a workaround but it's not ideal
