I haven't been part of the recent discussions on these logging efforts, but I wanted to mention that I'm excited about the potential here. I want to use this new tracing model to trace how many commits are walked by graph algorithms like paint_down_to_common().

I'm playing with some efforts here, and found one issue when the API is used incorrectly (I'll respond to the patch with the issue).

Thanks,
