I see both PoCs propose standard APIs. JVMTI is Java SE and VM 
independent so would be problematic to have normative reference to "JFR" 
in the spec. Once you converge on a direction then it would be 
interesting to see if it could be exposed using the JVMTI extension 
mechanism as that would give you flexibility to make available 
JDK-specific features
