So the argument for using this over a regular stack trace is that they don't have to ship megabytes of debug symbols. However they have seemingly just ignored the better option of only including function names in the debug table, which is obviously a much nicer option than having to use a web service to view you stack trace.
This isn't just a theoretical solution either, it's already implemented in LLVM: https://clang.llvm.org/docs/UsersManual.html#cmdoption-gline...
