There are times where its necessary, but the majority of usecases can be refactored to be immutable. Caching for annotation processors' classloaders helps kapt perform faster if you run many Gradle tasks consecutively. This is an excellent place for an operation like .map(): This example is clearly much shorter, with far less noise code around the important multiplication bit. You can also set an optional delay value per message. This makes applications safer through nullability declarations and expressing "value or no value" semantics without paying the cost of wrappers like Optional. Also, a static index file is generated in the index package/folder, called AdapterIndex.kt.
