In this thread[1] we're discussing problems with using DWARF directly for unwinding, not possible translations of the metadata into other formats (like ORC or whatever).

I wasn't talking about other formats. I was talking about preloading the information contained in DWARF into a more efficient in-memory representation once when your profiler starts, and then the problem of "the overhead is too high for realtime use" disappears.
