Be that as it may, but a core benefit of kotlin (as a developer) is that it has actively sought out good design patterns (eg. builders, composition etc.) and codified them into the language. In Kotlin often the best approach is also the most succinct one - which doesn't hold true for most of the platform-native languages (swift probably being an exception).

As long as it keeps doing that, even at the cost of a larger API surface area (or occasional backward incompatibility), I (and I suspect many others) will be quite happy to use it.
