In addition to my thinking this is just out of place (we already removed the similar JVMTI 
piggybacking from JNIHandles::weak_oops_do, though it had other problems too), note
that ZGC doesn’t call JNIHandles::oops_do at all (it uses the parallel oopstorage API), and
probably the only reason some of the other collectors (particularly G) still do is because
nobody has gotten around to making them use the parallel oopstorage API too.
