| This proposal introduces two new SwiftPM CLI options, `--trace-events-file` and `--enable-task-backtraces`, which can be used to analyze the performance of clean and incremental builds and identify common issues. |

Does this assume that swift-frontend traces are incorporated automatically when those become available, or would we need an amended proposal for that? I'm personally leaning towards the former, but maybe better to spell that out explicitly?

I'm considering the specifics of what's captured in the trace an implementation detail which could change in the future outside of evolution. But if we wanted to make merged traces opt-in since they add a lot of info that might not always be useful to non-compiler-developers, we might want a small follow-up proposal
