The Actor API has been deprecated for a very long time. The original intention was that a new Actor API would be developed to replace it, but that has been on hold for a long time and there’s no guarantee that it will ever be continued. So the current Actor APIs aren’t likely to be
removed any time soon since there’s no replacement, but there also won’t be any support for them should you find any issues with it. It is also only available for JVM targets so it cannot be used in multiplatform projects.
For those reasons, you probably shouldn’t adopt them for a new project, but there’s also not an immediate need to replace them in projects that have already adopted them. If you want to use that exact API, you might want to consider copying the
sources into your project so you can maintain and extend it yourself (it’s just a couple small files). Alternatively, there are other Actor libraries or different concurrency patterns which might serve your needs better, such as
kactor which was shared here recently, or
Ballast for an MVI model of programming
