Yes, Application Observability is a lot of the purpose of this. Instrumentation will be richer, more accurate, low cost, and able to be of value throughout the application for the purposes of tracing and profiling. What it will mean is that thing like https://github.com/open-telemetry/opentelemetry-go https://github.com/open-telemetry/opentelemetry-go will be able to use this to better instrument Go applications, and when OTel includes profiling (as well as traces) then you'll be able to use Pyroscope, Polar Signals, etc for that in addition to Tempo (or whatever you use for tracing), as well as using something like Grafana and Datadog to view all of the above. (I work for Grafana, but the above is relatively vendor neutral as yes we recently acquired Pyroscope and launched Grafana Cloud Profiles, and yes some of the people cited work for Grafana, but others are doing great work here too and it all benefits people who write and run applications using Go).
