Giving that up would be a huge > blow. IIUC, optimizing your application using standard (non-JITed) profiling tools would still be a win for the app when run under the JIT, because your are going to be trimming code / using better algorithms, which will tend to provide "orthagonal" speedups to anything the JIT does. The worst case would be that you hand-optimze the code to the point that the JIT can't help any longer, kind of like writing libc syscalls in assembler rather than C.
