Hello, I'm playing with a custom CoroutineDispatcher implementation using this implementation as a reference: https://github.com/Kotlin/kotlinx.coroutines/blob/master/reactive/kotlinx-coroutines-rx2/src/RxScheduler.kt However Delay interface is marked as InternalCoroutinesApi . Is there a good way to implement delaying?

If you really need to implement it, you can opt-in to use InternalCoroutinesApi, but you can also delegate delay to Dispatchers.Default

IFAIK delay is delegated to the Default dispatcher by default. What I want to do is to implement it "natively". Looks like implementing an InternalCoroutinesApi is not a good idea, binary compatibility may be broken in future.

Indeed, it can be broken, though, unlikely.
The main rationale behind being marked Internal — we are not happy with the current Delay API shape (methods, conctracts, implicity etc.), but neither have real-use cases nor time to properly design it.

Reporting your use-case to the issues would be a great start
