I respect the maintainer's decision, but I don't understand the justification.

> but when it was communicated with Mockito I perceived it as "Mockito is holding the JVM ecosystem back by using dynamic attachment, please switch immediately and figure it out on your own".

Who did the communication? Why is dynamic attachment through a flag a problem, and what was the solution? Why is "enable a flag when running tests" not a satisfactory solution? Why do you even need a _dynamic_ agent; don't you know ahead of time exactly what agent you need when using Mockito?

> While I fully understand the reasons that developers enjoy the feature richness of Kotlin as a programming language, its underlying implementation has significant downsides for projects like Mockito. Quite frankly, it's not fun to deal with.

Why support Kotlin in the first place? If it's a pain to deal with, perhaps the Kotlin user base is better served by a Kotlin-specific mocking framework, maintained by people who enjoy working on those Kotlin-specific code paths?

Mockito was indeed a poor fit for Kotlin. MockK is the one. Except I suppose for shops that have projects that mix Java and Kotlin and already have a Mockito tests.

Some complexities are discovered along the way, people don't know everything when they start.

They could also drop the support after some time, but then it would have created other set of problems for adoption and trustworthiness of the project.

Sounds like a problem that the Mockito team created for themselves, and like a problem only they can solve.
