Disclaimer: I'm the CEO of jClarity - a Java/JVM APM vendor.

You'll see plenty of APM vendors building on top of this technology. For years we've all tried to build lightweight mechanisms to get vital metrics out of the JVM with regards to Object and Execution profiling and although some strong progress was being made (Honest Profiler, Async Profiler et al), none of them are as comprehensive as Flight Recorder (Oracle did have the advantage of owning Java there).

Our own plans will be to refactor our ML diagnostic engine on top of Flight Recorder data. We're really, really looking forward to this!
