This doesn't remove annotation processors, just disables them running by default with no input from the developer (I assume if they were simply in the compiler classpath, which could happen by accident). As mentioned, it can still be enabled by its flag, and it's likely build systems will set that flag for you if you have declared you use annotation processors for your build.

I also disagree in the hardly used anymore part though, but I have no data.
