Can't speak for other people, but I remember experimenting with
glibc's backtrace(3) and being so underwhelmed by the usefulness
of the information presented that I thought incorporating it would
be mostly a waste of effort. Maybe there's an argument that it's
better than nothing at all; but I think we'd still be driven to
asking people to get stack traces with better tools.
