If you write library that uses Kotlin all the clients will transitively depend on Kotlin stdlib (+6k methods). Usually Java only solution is better imho. Same way I hate when third party android sdk uses Gson, or some other big libraries, your client can be not so happy about dependency to Kotlin. Many applications has policies about third party SDK and do not want integrate them if SDK is too big Depends on library size of course. If your sdk is really big maybe make sense to use Kotlin, tradeoff between happiness of your developers and happiness of client who should integrate this SDK.
