I wonder how this compares to grafana pyroscope, which is really good for this sort of thing and already quite mature:

As far as I'm aware, Pyroscope itself is not a profiler, but a place you can send/query profiles. OpenTelemtry is releasing a profiler, so they don't compare. One can be used with the other.

You can send profiles collected by opentelemetry to pyroscope.
