But Kotlin was farrrrrrrrrr from a "most used library". The risk of an unsupported language being used is much, much greater than using an unsupported library.

Libraries are non-trivial to remove from your code, but should not be tied to your code to the point that you will be required to completely rewrite your application like you would if you ran into issues with the language it's written in.

Say so to the people who is using RxJava or similar, whether they need to rewrite everything or not. In every program you need to take architectural decisions that affect how everything is build and a change on them could mean to rewrite everything. It can be a library or the programming language. JetBrains was supporting kotlin for Android, the same people that build IntelliJ idea (the base of Android Studio). But who is supporting RxJava? Imagine that the react community wants to make a move that will harm Android devs, so they change all the Rx*, including RxJava. Using kotlin wasn't a risk. Google said it will make it first class citizen, but do you really trust Google in the long term? They close products very quickly. I feel safer knowing that JetBrains is behind kotlin and not Google.
