Hey o/
I'm trying to implement the coroutines library on a JVM-based gaming platform. I was wondering if there is a possibilty to implement the `Dispatchers.Main` dispatcher (other than using the `ServiceLoader`). This would be useful, because a lot of the data needs to be updated from the main game loop. I'm aware that I could create my own dispatcher and I have done that. I just think that it would be more ideomatic if I could use the `Dispatchers.Main` Dispatcher.

I think there is a `setMainDispatcher` function or similar. I think it is often used in unit tests.

But what's the problem with the service loader?

setMainDispatcher is only in the kotlinx-coroutines-test package, changing what its service loader returns

I was just wondering if there was an officially supported way. The `MainDispatcherFactory` is marked as `InternalCoroutinesApi`.

Not public at the moment, but your use-case is quite compelling to stabilize this SPI. Please, file an issue to  <https://github.com/Kotlin/kotlinx.coroutines/issues|https://github.com/Kotlin/kotlinx.coroutines/issues>
