I don't see why it would be useful. Backtraces must be as accurate as possible, showing the exact sequence of calls, so that the user who debugs the problem could step through the relevant code. Omitting parts of a backtrace because they might be "ugly" or "confusing" would be a disservice, I think. I have never seen any practical use case where that would be a good idea. And I don't think I've seen a debugger that provides such a feature. Does anyone see a practical use case for such a feature?
