SAM conversion impacts these APIs:

 * Authenticator
 * Dispatcher.setIdleCallback(Runnable)
 * Dns
 * EventListener.Factory
 * HttpLoggingInterceptor.Logger
 * LoggingEventListener.Factory
 * OkHttpClient.Builder.hostnameVerifier(HostnameVerifier)

JetBrains [is working on][kotlin_sams] SAM conversions of Kotlin interfaces. Expect it in a future
