You can offer quite a lot of info (like backtraces, sampling profilers, etc.) for many runtimes just with the function name (which you can do without full on DWARF). The old LLVM JIT engine had a good NotifyFunctionEmitted hook for exactly this kind of usage. It's really about taking DWARF parsing / loading off the critical path for common use cases.
