There is static, load-time, and dynamic instrumentation. The 
Instrumentation API supports load-time and dynamic. If there is static 
instrumentation going on then it happens before the class bytes are 
loaded. Is that what you mean?

Or maybe you mean how the agent is deployed? The opt-in tracing right 
now is independent of how the agent is started so it works for 
-javaagent, Launcher-Agent-Class, and agents that are dynamically loaded 
via the attach mechanism. Maybe you are arguing that it should be 
limited to agents that are dynamically loaded?
