(Perfetto developer here)

The Perfetto UI already supports flamegraphs btw (we use it for memory profiling and CPU stack sampling). We've never bothered to implement it for userspace slices because we've never had high frequency data there to make that a worthwhile view of the data.

Contributions for this upstream are very welcome :)
